<br />
Is there such a thing as too many 3D printers? I contemplated this over the weekend, as Facebook "memories' reminded me that I purchased my Makerbot Replicator 1 exactly three years ago. Looking around my classroom, I realized I have owned 10 3D printers. So, on this anniversary of sorts, I present: Where are they now?<br />
<br />
1 Original Printer bot<br />
<br />
[pic of printer in bin]<br />
<br />
2. maker bot rep 1<br />
<br />
3. Cube<br />
Our first Cube performed great until a problem forced us to replace it. The replacement also worked well, at least until it caught fire.<br />
<br />
4. Printerbot (donated to BHS)<br />
<br />
5. Printerbot simple metal<br />
Gifted by Printerbot before maker fair 2014, the kids abandoned it, and it now resides Sam.<br />
<br />
6. Droplit<br />
We got this as a kit that some Maker Club kids assembled. Unfortunately, the kids that put it together forgot to document the process, and it now sits in a corner. We plan to start repairs after Maker Faire, but until then, it will remain in it's corner, starring down on those who abandoned it.<br />
<br />
7. Afinia<br />
The Afinia is the most reliable printer we have used to date. The print quality good, but the rafts are hard to get off. It currently is suffering from a clogged extruder, and will be fixed soon.<br />
<br />
8. maker bot rep 1<br />
We got this one for 90$ at a maker clearance event brand new. It worked fine for a while, but there is currently<br />
<br />
9. maker bot rep 1<br />
This was also from the clearance event, and was also brand new.<br />
<br />
10. Buko bot<br />
We the Bukobot got to act as a more "kid friendly" printer (also because it could print upside down), but there is something wrong, and cannot move on the z axis, and will make grinding noises if attempted.<br />
<br />
<br />
Others (add to the list)<br />
2 Cetus<br />
1 bioprinter (school purchase)<br />
3 Ultimakers (school purchase)<br />

<div style="text-align: left;">

<div style="text-align: left;">
As we are nearing winter break and are in the midst of the holiday season, we decided to build a three-dimensional, recyclable, life size Christmas tree, because, well, why not?</div>
</div>
At the start of Maker Club on Thursday, December 13th, Ms. Mytko gave us a 6 foot PVC pipe and told us to make a tree.<br />It involved a lot of trial and error, and at the beginning we were very disorganized. We had about 8 people working on the tree. About 2 or 3 on making the base structurally sound, 1 person on making the pyramid on the top, 2 people on making squares, and a couple people milling about, unsure about what to do. As time continued, we slowly became more organized. We had two people on cutting squares, and three people on cutting holes in the center of the squares so they could go onto the PVC pipe. We couldn't possibly cut holes in flat cardboard slabs fast enough, until Ms. Mytko came by to give us a suggestion. We cut little x shapes into the center of the cardboard like little flaps and the forcefully shove them onto the PVC pipe. Then we really got into motion. WE had a whole system. One person cutting more squares and passing it to another 2 people finding the midpoint of each square, and us passing those to 2 other people to cut the squares, and then finally, to the last person who tested them on the tree "trunk."<br />
By this time, it had started to grow dark and we hadn't put anything on the tree yet, so with help, we lined all the squares up from biggest to smallest and applied them to the trunk. After around ten minutes of forcing cardboard on pipe and duct taping (of course) everything for structural support, we topped it with the pyramid and admired our work. Someone put the first cardboard ornament on the tree! We threw some fairy lights on it to add to the effect and our Maker Tree was complete!<br />
In Friday Maker Club, people made more ornaments for the tree and hung them up!<br />
It was a great success<br />

The outside is a normal Ritz box with letters cut out but the inside has two smallish speakers. We were hoping to make it Bluetooth although the thing we were using (sonicIQ) although we didn't get it to work. Although the sound is slightly muffled in my opinion it works great. There is a whole on the bottom to let the power cord through and the hole for the heat sync but other than that it looks like a regular Ritz box with negative letter spacing.<br />

One week ago, we loaded our rented van with kids, chicken crafts, and our HTC Vive, and headed off to the San Mateo Maker Faire. Sunday night we returned with far fewer button-making materials, tired and happy kids, and an Editor's Choice blue ribbon for our project, <a href="https://makerfaire.com/maker/entry/65370/">Chicken VR</a>!<br />

<b>First, a little backstory on Chicken VR: </b><br />
<br />
At Black Pine Circle School, we're obsessed with chickens. In the science room, there is a chicken calendar, multiple chicken posters, and each of our non-Chromebook computers are named after chicken breeds. The 7th grade science class hatches chickens just about every year, but these birds usually are returned to the farm after a couple of weeks. Until last year, when the garden educator and some students got together to build a chicken coop. After a 2017-year end ceremony, we now have chickens living on campus.<br />
<br />

<br />
When we were brainstorming for East Bay Mini Maker Faire, we wanted something chicken-related, but also tech-related, with a maker element. We had recently bought our HTC Vive (a few months ago) and wanted to learn more about developing software for it. This is how we got the idea for Chicken VR. It's a first person chicken simulator in virtual reality. You can walk around, eat, drink, and lay eggs.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhoc-M50RsDbeoAaxx4HTzwVQNwIajJaJ0EuDXlShkYYLPYPhXzSpqPKsEmc6O1ZYCdjv7gspZkAlp4l2K9HENYzcH-6UR5ZQb-jvEXor_EDui6ScFkogNgqTH0oGt_uJEUdNlPLbCUospX/s1600/elanb18+eriks18+ruebenl18+gigi+1718+Chicken+VR.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1067" data-original-width="1600" height="265" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhoc-M50RsDbeoAaxx4HTzwVQNwIajJaJ0EuDXlShkYYLPYPhXzSpqPKsEmc6O1ZYCdjv7gspZkAlp4l2K9HENYzcH-6UR5ZQb-jvEXor_EDui6ScFkogNgqTH0oGt_uJEUdNlPLbCUospX/s400/elanb18+eriks18+ruebenl18+gigi+1718+Chicken+VR.JPG" width="400" /></a></div>
<br />
<b>Our first step was research. </b><br />
<br />
As with any good project, we wanted to see what was already out there. We searched the Internet and was momentarily crushed to discover that a Oculus Rift <a href="https://www.youtube.com/watch?v=893tQAIazvY">Chicken Simulator</a> already existed! Though it has some really interesting features, we knew we wanted to personalize our first-person chicken experience to match our chickens at BPC. Plus, the Vive would allow users to walk around in real space, instead of having to sit in a chair.<br />
<br />
Another project, <a href="http://www.secondlivestock.com/">Second Livestock</a>, from Iowa State University assistant professor Austin Stewart "imagines how VR goggles could make chickens believe they’re free-range, even when they’re not. They can explore a virtual grassland, and with future iterations of Oculus, even peck at the ground and bob their heads around to take in the landscape at different angles." (via <a href="https://techcrunch.com/2014/05/15/an-oculus-rift-for-chickens-gives-animals-the-freedom-to-roam-without-the-roaming/">TechCrunch</a>) Strange, right?<br />
<br />
There is also a <a href="https://scratch.mit.edu/projects/73311484/">Virtual Chicken Coop</a>, "the most realistic chicken coop simulator on scratch, currently featuring 10 different breeds of chickens!"<br />
<br />
But, we believed we had something different. Besides, can there be too much Chicken VR?<br />

Originally, we brainstormed a design where the trackers would actually be your feet. However, we realized that if we wanted users to teleport, this presents a problem. We thought about getting four controllers, and eventually settled on the design with two controllers held in hands.<br />
<br />
We used TinkerCAD to create the wings out of simple shapes. These wings are attached to the controllers and you can flap and teleport. We used Fusion 360 to create the virtual model modeled off our actual school coop.<br />

<div class="" style="clear: both; text-align: left;">
Finally, we used Unity to design the environment, adding terrain and taking full advantage of the "Mass Place Trees" button before applying various textures to complete the look. We worked on the physics of the wings and eventually added rotation to body movement and made sure the body resizes based on head height to accommodate a wide range of users. </div>
<div class="" style="clear: both; text-align: left;">
<br /></div>
<div class="" style="clear: both; text-align: left;">
We added teleportation and a health, water, and food system with HealthTracker script. In Chicken VR 1.0 (which we brought to the East Bay Mini Maker Faire) when the beak touched food or water, your scores would increase and there was a dehydration timer involved as well as a health loss if food or water is empty.</div>

<b>Version 2: 2018 San Mateo Maker Faire</b><br />
<div>
<br /></div>
Before Bay Area Maker Faire (a few weeks before), we removed the health, food, and water tracking systems and added some new features. Now you can lay eggs when you pull the trigger and fly. There's even a purple hand that follows you around and feeds you a worm periodically. There are new sounds, which include "chicken eating," "chicken drinking," "chicken background," "slurp," and "flap."<br />

Besides Chicken VR (which often had long lines) the maker club kids had additional chicken crafts available. People could make chicken buttons, or other chicken-related crafts. The button backgrounds came from a coloring book titled <a href="https://www.amazon.com/Exotic-Chickens-Coloring-Everyone-Relieving/dp/1510712259">Exotic Chickens: Coloring for Everyone (Creative Stress Relieving Adult Coloring Book Series)</a>. The button machines were, as usual, a big hit with kids and adults alike.<br />

It takes some experimenting to get right, and you have to use the right kind of battery, but otherwise it works pretty well.<br />
<br />
We learned in our first attempt that it won't work on lids for mason jars, because the surface isn't conductive. You'll want to test for conductivity on your material before you try to do anything. We were initially misled, because it "worked" the first time. In reality, water had leaked under our stencil, completing the circuit. Once we made a tighter seal (by using sticker paper for our stencil), it was no longer conducting anything and no longer worked.<br />
<br />
Eventually, I successfully engraved in a sheet of stainless steel using a 12v battery.<br />
<br />
First, you need to prepare the metal surface. Clean it using rubbing alcohol (91%). (As mentioned, the lid in the picture won't work, but it does illustrate the cleaning step.)<br />
<br />

<br />
Soak some Q-Tips in a mix of vinegar and salt. You can also use water with just salt but it won't be as strong. The amounts don't matter but you can watch the video (1:28) to get an idea.<br />
<br />
<div style="text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjrOzaRiiufOtfEGp8N-ZBUA8xK9sD5tYOja9CbW4kk4PfC-Y7UZBxXXTbrWdFl4JxR5goLkDTKVnSuYJaUmgYnu8wmbXsfglaHK6V8iIZfEHWhdjUwbgrXRA59dHAadxzCDXM5nuwUeMA/s1600/IMG_0517.JPG" imageanchor="1"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjrOzaRiiufOtfEGp8N-ZBUA8xK9sD5tYOja9CbW4kk4PfC-Y7UZBxXXTbrWdFl4JxR5goLkDTKVnSuYJaUmgYnu8wmbXsfglaHK6V8iIZfEHWhdjUwbgrXRA59dHAadxzCDXM5nuwUeMA/s400/IMG_0517.JPG" width="400" /></a></div>
<br />
You need a power source. We tried using a bunch of 9v batteries but found that this lead-acid 12v battery worked better.<br />
<br />
<div style="text-align: center;">

<br />
I laser cut a name tag onto transparency paper with a stencil font and stuck it on with some blue tape to prevent the liquid from leaking around the stencil, but you can also use sticky stencils or something else. The video also shows how to use stickers and nail polish to make more complex shapes.<br />
<br />
<div style="text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhjKgfHUfG4PI0wnIB3gZRMfyjvkkAASU2TyondmrNtPnuAxWCbu1hNCMsEQ7QFqnx5f3c_kfN9x1Izu-FrzATFgTOZr0pMaQcceSyMobv1Fon3YSstk_0VBxc8-fRnBrIRcjGm5gpd3VA/s1600/IMG_0520.JPG" imageanchor="1"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhjKgfHUfG4PI0wnIB3gZRMfyjvkkAASU2TyondmrNtPnuAxWCbu1hNCMsEQ7QFqnx5f3c_kfN9x1Izu-FrzATFgTOZr0pMaQcceSyMobv1Fon3YSstk_0VBxc8-fRnBrIRcjGm5gpd3VA/s400/IMG_0520.JPG" width="400" /></a></div>
<br />
Connect one end of the battery or power source to the metal and one end to the end of the Q-Tip, making sure the alligator clip on the Q-Tip won't touch the metal surface.<br />
<br />
<div style="text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjp9Fc_t4EVoSKlqaPz7GTz-kdkJqAMhSnrsnYeyOTzxOrUG2yMPMhjyG4DmPLhH_tC6oYzfQuX6EH9W12r2WDfXoY1hgoshVMm_Mvcgmj9pM6Je11yNWqagZ737PiuiqDQh8R5YAc1ULA/s1600/IMG_0518.JPG" imageanchor="1"><img border="0" height="253" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjp9Fc_t4EVoSKlqaPz7GTz-kdkJqAMhSnrsnYeyOTzxOrUG2yMPMhjyG4DmPLhH_tC6oYzfQuX6EH9W12r2WDfXoY1hgoshVMm_Mvcgmj9pM6Je11yNWqagZ737PiuiqDQh8R5YAc1ULA/s400/IMG_0518.JPG" width="400" /></a></div>
<br />
Put the Q-Tip on the metal in one spot for around five seconds and then move it to the next spot. It makes a bubbling sound and some smoke. I wiped any liquid off of the surface after each letter.<br />
<br />
<div style="text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiRIkxy7rR1GkhhdxV_9iiPCaM32kb2nd8_bVgLywyBTWHUuHPecSqvF5jFK9SJCa_VNO4VI_ZABA2AsL1T6TtieDwg6MMLvC9yqV3FuabwjN5WesEe79GVd4m9pY0-j1gnW-yDrvwucXA/s1600/IMG_0529.JPG" imageanchor="1"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiRIkxy7rR1GkhhdxV_9iiPCaM32kb2nd8_bVgLywyBTWHUuHPecSqvF5jFK9SJCa_VNO4VI_ZABA2AsL1T6TtieDwg6MMLvC9yqV3FuabwjN5WesEe79GVd4m9pY0-j1gnW-yDrvwucXA/s400/IMG_0529.JPG" width="400" /></a></div>

We, and other Glowforge potential owners repeatedly received delay-of-shipment emails, to the point where many people began to jump ship.<br />
<br />
The space had been taped off for so long and it had become a joke. Someone wrote "The forgotten dream," back in 2016, and earlier this year, someone else added "We will love love u and cherish u what scared u away?" We still don't know who wrote these messages.<br />

<br />
Sunday, November 5, we assembled for the unboxing.<br />
<br />
We made the same mistake we make every time we open a box with something expensive in it: we cut the tape and then realized we had opened it wrong. We carefully turned it on its side and took the laser cutter out. Looking at the unboxing guide, with the link conveniently located inside the box, we found that we shouldn't have even cut that tape.<br />
<br />
Once we got everything out of the box, we removed the protective foam and assembled the "print head."<br />
<br />
We cut out some cardboard to seal the window we were venting the exhaust through, and set up a table near the window. Then we plugged it in and turned on the machine. It worked as expected, making some bubbling noises from the water-cooling system. The setup process was super simple and only required us to connect it to the school's WiFi before we could start making things from their web based software (that can run on a Chromebook!).<br />
<br />

<br />
<br />
Someone drew a simple not-so-accurate square on a piece of paper and placed it in the machine so that we could scan it. We scanned it and then put some acrylic in the machine. When we went to cut, we ran into a problem.<br />
<br />
Here's the thing: the Glowforge was so popular because of how easy it is to use. In order to make it this simple, they made their own material presets. These material presets are only for their "proofgrade materials," which means we can't cut with our own materials. They do have a way that you can set it yourself, but the controls are very ambiguous and you can't save presets. We also didn't have our introductory proofgrade material kit, it came the day after.<br />

So, we estimated, choose only to engrave, and ended up with this >>><br />

This month, we received some <a href="https://ninjatek.com/products/filaments/ninjaflex/">NinjaTek Cheetah flexible filament</a>, which is pretty exciting.<br />
<br />
Next, we had to decide what to print with it! Lat time we got a sample of flexible filament, we re-printed the rubber feet of the 3D printers that somehow always seem to get lost in a middle school classroom.... <br />
<br />
Since we were experimenting, we went on Thingiverse to find something cool. We downloaded the file <a href="https://www.thingiverse.com/thing:739806">Miniature Robotic Hand for NinjaFlex</a> by Open Bionics - it prints in one piece!<br />
<br />
As you can see in the video below, the final product is pretty cool!<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<iframe allowfullscreen="" class="YOUTUBE-iframe-video" data-thumbnail-src="https://i.ytimg.com/vi/Ab9XOPMlSLQ/0.jpg" frameborder="0" height="266" src="https://www.youtube.com/embed/Ab9XOPMlSLQ?feature=player_embedded" width="320"></iframe></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
Of course, what's the next step? Print a BIGGER one. This print used the same type of filament, but was significantly bigger.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAV41TtSVglX1UHcRYMSI1EfuFpJrZ8bpBPY70YZv5_DuCisxK7mqQfhyphenhyphenLIRMg_MQsngu1igxs1GuOdBO5rR6XZWMVeqngXOpkrX1cRYEA4KmCgEZdnruAL-k9xsX2VnGLMGyFmTh-KZl2/s1600/hand+-+2.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAV41TtSVglX1UHcRYMSI1EfuFpJrZ8bpBPY70YZv5_DuCisxK7mqQfhyphenhyphenLIRMg_MQsngu1igxs1GuOdBO5rR6XZWMVeqngXOpkrX1cRYEA4KmCgEZdnruAL-k9xsX2VnGLMGyFmTh-KZl2/s400/hand+-+2.JPG" width="400" /></a></div>
<br />
We learned something surprising! When it is this big, it is too floppy to function in the same way, so the final product was rather dull.<br />

This is not unusual. The standard procedure is to take a look at the extruder and maybe unload and reload the filament, checking for errors. Unfortunately, one of our students decided it would be a good idea to take the entire 3d printer apart. The student took apart the entire extruder and, in the process, broke the temperature sensor and the heater cartage.<br />

Despite our teacher's constant reminders to document, there was no documentation, except photos that were lost (the photos in this post were taken after the disassembly). After disassembly, what used to be a 3d printer extruder looked like this: </div>

<span style="font-family: inherit;">So, we were left to reassemble a broken 3D printer with very little documentation and no recollection of "what happened." The Ultimakers came with an extra "Hot End Pack," which includes a temperature sensor, a nozzle block, and various other extruder related parts. At first, we thought this would solve the problem. But ends up the pack did not come with a heater cartridge, so we were stuck. The Dynamism site (where we first ordered the printer) sold only a few, more consumable, parts--and not the parts that students might destroy. </span><br />
<span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;">Luckily, Ultimaker support eventually clued us in to the <a href="https://fbrc8.zendesk.com/hc/en-us">fbrc8 Ultimaker warranty site</a>. This was VERY helpful! We found a </span>heater cartridge and <span style="font-family: inherit;">ordered one. </span><br />
<span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;">Back in the classroom, we replaced the broken temperature sensor with the one from the "Hot end pack" and the heater cartridge from the fbrc8 warranty site using this fbrc8 resource: </span><a href="https://fbrc8.zendesk.com/hc/en-us/articles/206888416-Changing-Heater-Cartridge-and-Temp-Sensor-2GO-" style="background-color: white; font-family: inherit; text-transform: capitalize;">Changing Heater Cartridge And Temp Sensor (2GO)</a>. We had to open the bottom of the Ultimaker to plug the heater cartridge back in. It was good practice in reading the instructions very carefully!<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
<br />
<div>
<span style="font-family: inherit;">Finally, for reassembly, we followed the <a href="https://fbrc8.zendesk.com/hc/en-us/articles/206151456-Changing-Parts-in-the-Print-Head" style="background-color: white; text-transform: capitalize;">Changing Parts In The Print Head </a>steps for disassembly and reassembly, even though most of our parts were already... ahem... disassembled. We also used the instructions: <a href="https://ultimaker.com/en/resources/253-re-assembly" style="text-decoration-line: none;"><span style="color: #1155cc; vertical-align: baseline; white-space: pre-wrap;">hot end assembly</span></a><span style="vertical-align: baseline; white-space: pre-wrap;"> |</span><a href="https://ultimaker.com/en/resources/252-disassembly" style="text-decoration-line: none;"><span style="color: black; vertical-align: baseline; white-space: pre-wrap;"> </span><span style="color: #1155cc; vertical-align: baseline; white-space: pre-wrap;">hot end disassembly </span></a></span><br />
<br />
Eventually we reassembled everything and were proud of our efforts when it printed flawlessly once again!<br />

On May 26th, BPC had its first official <a href="http://makerfaire.com/global/school/">School Maker Faire</a>. (We've done unofficial "micro-maker faires" in the past.) What started as something we did in an after school club three years ago (making) has now fully infiltrated seventh grade science!<div>
<br /></div>

<span style="color: black; font-family: "arial"; font-size: 11pt; vertical-align: baseline; white-space: pre-wrap;">I Screen Printed onto old shirts to raise awareness for the LGBTQ+ and mental illness communities. I noticed that representation in the media of the LGBTQ+ community is sparse, and there is almost no representation of people who fight with mental illnesses. Seeing yourself represented in the media can change someone's outlook, make them feel hopeful, and can show them that they are not alone. Lack of representation can isolate groups of people and I wanted to combat this problem with creativity. At first I wanted to make a clothing line, however time and material constraints proved that to be unfeasible so I decided to try screen printing. I had never screen printed before, so I had to learn from Wikihow. I started out by coming up with phrases to ink onto the shirts, for instance “Dear Homophobes; Boo!”. </span><img alt="DSC08469.jpg" height="376" src="https://lh6.googleusercontent.com/11e2anllBusjAJZhgCB-Lmo6VX1w7tRMXC0cIIUmCZ9f9TfFHF-MRHXi6wTbInKqLgLvhh_ALvn8Gk7ep_jp8OU2SXU9wGpiLzFPf_3-tU3lR95ItdrFC5U9ZzfuZrFb-UsHfGlL" style="border: none; transform: rotate(0rad);" width="599" /></div>

I decided to try printing it out first, then using an exacto knife to trace the lines. This worked well but it still wasn't time efficient. I finally attempted to laser cut my design, this was not only time efficient but it was also a great learning experience. I cut old undershirts and screen printed my phrases onto them. This project costs around 45 dollars for the baseline materials but it can fluctuate significantly for the unnecessary materials. </span></span><br />

I would enjoy marketing this into a business on Etsy, I will continue to screen print at home and I will possibly sell some shirts. If you are interested in this project make sure you set the ink into the shirt before you take off the screen, this will ensure better quality prints. Don’t give up when the ink smears, or doesn't come off, you can always go over your design with an ink dipped pencil. If you don't focus on the mistakes, but rather on the quality parts of your print, you will end up a lot happier!</span></span><br />

For our school maker project (in science class), we wanted to create something that kids everywhere would be interested in using, and we also brainstormed different ways to spread our creations beyond the school to reach a wider audience. We wanted to use our knowledge of 3D printing. As we saw the rise of fidget products all over our school and all over the country, we realized that we had found our project: we decided to 3D print some fidget spinners that we designed ourselves out of recyclable filament. There were some technical challenges that we experienced: for instance, the design we created ended up with some overhangs, which you can see in the image above. To deal with this, we decided to use dissolvable support material to hold them up. We also had to make a decision about what printer to use of the ones available to us at school. We chose to use a Replicator 1st Gen because of its dual extrusion capabilities, and this served us pretty well.<br />
<br />
At first we were just making very colorful objects with two different colors of filament. We made <a href="https://www.thingiverse.com/thing:329436">this two color frog</a>, along with some other things. After making a few multi-color prints, we quickly realized that this printer wasn't made just for printing with different colors. There must be some other reason that they made a dual extrusion printer. After doing some research, we found out about <a href="https://store.makerbot.com/filament/dissolvable-filament/">dissolvable filament</a>. With dissolvable filament we would be able to make very complicated prints and dissolve the support material in <a href="https://www.amazon.com/Blubonic-Industries-d-Limonene-Medicinal-Degreaser/dp/B009SSGW48/">limonene</a>. One of the biggest problems with 3D printing is that you can't get support material out of very small places. With dissolvable filament, it was also possible to make moving parts in one print. Our first test was to make <a href="https://www.thingiverse.com/thing:12342">this gear thingy</a>. We then decided we wanted to make more, and designed a different two geared fidget. However, we had a problem, the sides were not fully connected and the model often broke. We redesigned it, and it look something like this:<br />

<span style="font-size: small;"><span style="font-family: inherit;">We used <a href="https://www.tinkercad.com/">TinkerCAD</a> because of its very straightforward design software that all of our group members knew how to use and the fact that we could use geometric shapes very easily along with the community shape generators. <br /><br />To get started with our project, we started out with a simple dual geared fidget because we had no experience making this type of project before. Starting simple was helpful, and we later were able to get more complicated and make things like triple gears and quad gears. <br /><br />One of our greatest challenges was when one part of the 3D printer we were using broke. We were able to re-3D print this part but it was a bit of a hold up. We also had to come up with a way to fix the windows for our 3D printer because our print’s kept peeling and we needed to stop drafts from reaching the heated build plate.</span></span><br />

Throughout this process we learned not to rely on machines because machine failure is common. We also learned that even if you are using a very baseline software, you can still make amazing creations with it, it just may require more work.<br />

If we wanted to continue this project, we could create more gear designs using ball bearings. This would be hard though because we might have to not print the gears as one piece so we could insert them, or we would have to put them in mid print. <br />
<br />
Our advice for other people who do this project is to start early and use a web based software (like <a href="http://tinkercad.com/">tinkercad.com</a>) so that they will be able to access and change their project from different places.<br />
<br />
An estimated cost of materials in this project (not including the 3D printer) is about $40 because of the fact that the slicer and the design program (Tinkercad) were both free, so the only costs we had to cover were filament (ABS and HIPS) and electricity. This $40 could cover many, many gears, because they are almost hollow and therefore very efficient with the material.<br />

One day while we were waiting for a set of gears to print we chose to make a website at <a href="http://www.thegearmakers.wixsite.com/gearmakers">www.thegearmakers.wixsite.com/gearmakers</a>.
Through our project we had to fix the Replicator about six times and
replace some parts. By the end we had created four production lines. And
already finished two of them (dual geared basic and dual geared +). We
thought that with four different products to choose from we had finally
done what we had meant to the whole time, we had finished with our
fidget production. </div>

The Cetus is a pretty new 3D printer that was on Kickstarter for pre-order late last year and was meant to deliver this January. We bought this directly from Cetus and it came in about 2 weeks from China. As you can see, it does require some assembly, but it is not too bad.<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPPSKw9fiFg0Hv2ipsQmOtpHcj_pV4xKCt-RMeS8HHqLI9oQwL6KLGR8qmPrpnplX65cNgEsfrIK9KS-IY-Rs7HGNd7fWB3uiW7Qyfh2iSAjn9rJXgtiBW114VAjoyEHpwbrAvTchhOQHa/s1600/DSC05296.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="1067" data-original-width="1600" height="211" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPPSKw9fiFg0Hv2ipsQmOtpHcj_pV4xKCt-RMeS8HHqLI9oQwL6KLGR8qmPrpnplX65cNgEsfrIK9KS-IY-Rs7HGNd7fWB3uiW7Qyfh2iSAjn9rJXgtiBW114VAjoyEHpwbrAvTchhOQHa/s320/DSC05296.jpg" width="320" /></a><br />

The Cetus seems like an amazing deal for $300. It removes all of the flashy boxes and accessories most of the new 3d printers have today, and gives you a great experience. With linear guide rails, a 7 inch cubed build area, wifi printing ability, and an easy to use software, it even came with a nozzle unclogger and snippers to cut filament and such, what's not to love? Well, not much.<br />
<br />
The only bad thing is the Z axis is not supported without power. This means when you turn off the printer when it is at the top (or its idling position) the printer head will glide down and rest into the build plate. You can print a clip or lever to hold it in place and stop it from doing that so its an easy fix.<br />
<br />
From the first test print, we can see it is super super great quality for a budget 3D printer. I do have to say that the next time anyone asks me for a suggestion on a nice, budget 3D printer, the Cetus is going to be the first thing I suggest. Its great for a classroom or your first 3D printer. <br />

<br />
I was also surprised when I printed an overhang stress test and it didn't start stringing until about 60˚, and even after that it still printed with very very minimal strings (even to 90 degrees!!).<br />
<br />
I was amazed, I then loaded up the Make Benchy boat stress test. Once again I was astonished at the quality of the overhangs and pure detail around every corner. Comparing it to the Afinia, the Cetus lacks a heated bed (and that means no ABS but it doesn't matter anyways because our classroom is trying to move away from ABS) and currently in their shop is a beta heated bed anyways so if you really wanted it you could get it. On the flipside, the Cetus has a much larger bed and is also quite a bit cheaper.<br />
<br />
I'm excited to continue using this 3d printer as it is by far my favorite.<br />

In all seriousness, I am proud of my students for building this <a href="https://www.moogmusic.com/products/etherwave-theremins/etherwave-theremin-kit">theremin from a kit</a>, then troubleshooting it until it actually worked. Now, they are experimenting with the goal of eventually producing <a href="https://www.youtube.com/watch?v=K6KbEnGnymk&list=RDK6KbEnGnymk#t=25">music</a>, instead of sounds resembling the screeching of a tortured cat. You can read a little about the theremin's interesting history <a href="http://www.cbsnews.com/news/the-theremin-a-strange-instrument-with-a-strange-history/">here</a>, or watch the video about the science of how it works below:<br />

Kodon is more of a sculpting program that you get a basic shape and from there you can push/pull/smoothen a material using the controllers of the HTC Vive. Whereas Gravity Sketch is a program similar to <a href="https://www.tiltbrush.com/">TiltBrush</a>, but instead of having a colored brush, it's a 3D sphere that you can draw with. Both programs are in their early developmental stages and not very close to being a complete software but are both fairly easy to use and self explanatory.<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjKwV2c2GtG5T2ajy_-TmeaTn5iot9Ganqlpoyix_qC4HicJc7M6guFN1guIVkwUbtqtWvae-NbJmN85P0Ma96CtISySFmgmDD5-zEfAXkYOe83mompl7gzEPWhvrdVPVqfUNca76iAAWQW/s1600/0tag+1617++-+1+%25282%2529.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="213" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjKwV2c2GtG5T2ajy_-TmeaTn5iot9Ganqlpoyix_qC4HicJc7M6guFN1guIVkwUbtqtWvae-NbJmN85P0Ma96CtISySFmgmDD5-zEfAXkYOe83mompl7gzEPWhvrdVPVqfUNca76iAAWQW/s320/0tag+1617++-+1+%25282%2529.JPG" width="320" /></a>The first program we got was <a href="http://store.steampowered.com/app/479010/">Kodon</a>. It was already on Steam and was just like downloading any other games. Once I put on the headset I thought that someone was standing in front of one of the sensors because it was flashing and almost re-calibrating. It slowed down and I eventually got used to it. Its most likely due to the capabilities of our computer not being able to catch up with what the software is doing.<br />
<br />
<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEimWgo2iDVftaP8FzzwvCuVQ1epByi9EscD5aixmCowiEDgloJ2l1GkoYGz3yyxxqVrEQ-FazI4vrs3Qrj6GyuitnjipmQgP4KJwYT_jBr4ftexbZCA0LsT2lXJ9zWdajQ1kHTjBj9e_ZJ3/s1600/pig.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="150" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEimWgo2iDVftaP8FzzwvCuVQ1epByi9EscD5aixmCowiEDgloJ2l1GkoYGz3yyxxqVrEQ-FazI4vrs3Qrj6GyuitnjipmQgP4KJwYT_jBr4ftexbZCA0LsT2lXJ9zWdajQ1kHTjBj9e_ZJ3/s200/pig.jpg" width="200" /></a>Another thing that was confusing was the seemingly infinite number of menus that seem to change randomly, but after a few minutes of finding my way, I was able to navigate to any screen from anywhere. It was still a bit confusing but after fiddling with some settings I understood and was able to use the controller easily. One of the settings is turning the controller around so you can use it more as a pen than a controller. It was slightly easier to use but still had its glitches. After using this for quite a while and then seeing the final result, I concluded I didn't want to use this software on this setup again. It was quite difficult. In the end, it may not look like much, but this pig-head model is my first tangible 3D model designed in virtual reality!<br />

<br />
Then I tried <a href="http://store.steampowered.com/app/551370/">Gravity Sketch</a> which was more so what I wanted. As soon as it booted up it was very blank. Nothing at all. But the controls were surprisingly easy to figure out how to use. In a matter of minutes I was proficient in using it. As I said before, it is very similar to <a href="https://www.tiltbrush.com/">TiltBrush</a> After finding the download button I decided to start my first real project in Gravity Sketch. Making it was very easy to do and exporting and saving was easy. My one complaint of Gravity Sketch would probably be that for some reason, all the strokes are saved separately in one model, making my arch nemesis overlapping shells. It adds one step too many between drawing to print. I need to drag it into Meshmixer and combine all objects, however when you have too many strokes (as mentioned, due to my computer's processing power), it crashes. But once I do wait for an hour for it to load, the outcome is well worth it. I could then print it on the 3D printer and it was a very nice model. The software is very easy to use even though its in its beta stages. - Enzo, 8th grade<br />

I sincerely recommend you do this as I spent 4 and ½ hours with my friends making these, my friends learned how to make them in about 5 minutes, and then we made them for the rest of our sleepover. We found them very, very addicting to make. We also found that after a hour or so, the motions become automatic. You should try this if you want a easy, fun craft to do! </span><br />

Every project goes through iterations, and in some cases <i>a lot </i>of iterations. Recently I've been working on a necklace and a modeling project that have both gone through <i>a lot </i>of iterations. The necklace (a model of a constellation, originally designed to test out the copper filament on our Afinia), was the first copper-filament project we'd done on the Afinia for a while, and I ran into some issues getting it to print well, as well as some general workflow issues.<br />
<br />
At first, the printer wouldn't connect to the laptop, but that was resolved by unplugging and plugging it back in several times. This has turned out to be a fairly common problem with the Afinia, and we haven't figured out another solution yet.<br />
<br />
Once we had it printing, the raft printed just fine, but it started to air-print after that. So I restarted it. And it failed again. And again. So I opened it up, cleaned out the inside, and ran it again. This print worked, but was the wrong size (iteration 1). So I ran it again. And it failed. So I opened it up again, cleaned it, and ran it again.<br />
<br />
This one worked, but was missing some parts due to a software error (iteration 2). and some minor software and design issues later (iteration 3), I switched printers. Iteration 4 was quite nice, but the copper filament we have doesn't work on the Makerbot. So, back to the Afinia for iteration 5. A little analog repair work later (did you know a soldering iron can be used to melt 3D printed plastic?), iteration 5.5 was the final product.<br />

<br />
My next project, a model for one of my high school classes, also started on the Afinia. It tipped over during the first printing (iteration 1), so I cut off the bottom (iteration 2) and tried again. This one peeled off the build surface (iteration 3), so I switched printers again, to the Makerbot. Iteration 4 printed quite well, making this project slightly shorter.<br />

Ends up, you can't just import in if it is made out of triangles and not quads. The easiest way to test this is to import and right click and see if it gives you the option to convert to B-REP Surface. If it doesn't we have to go the long way to get it into Fusion 360.<br />

My goal is to do this in less than 48 hours. The basic process includes the following steps: <br />
<ol>
<li><span style="font-family: inherit;">3D scan</span>ning of the face</li>
<li><span style="font-family: inherit;">Design c</span>hocolate CAD file</li>
<li><span style="font-family: inherit;">Export</span> design<span style="font-family: inherit;"> for Othermill</span></li>

<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<span style="font-family: inherit;"><span style="color: purple;"><br /></span></span>
<span style="font-family: inherit;">To start out I needed to capture my teachers head in 3D. To 3D scan something there are many options, like using 123D Catch, and Remake both utilize your smartphone or DSLR camera to create 3D scans. I opted for an easier option using the <a href="http://talesofa3dprinter.blogspot.com/2015/02/3d-scanning-with-structure-sensor.html" target="_blank">Structure Sensor.</a> It is a sensor that clips on to the back of an iPad. I choose it because it takes me 1-2 minutes to scan a head instead of 5+ minutes for 123D Catch and Remake. To scan somebody with the Structure Sensor all you have to do is walk around them then the app, <a href="http://itseez3d.com/">ItSeez3D</a>, processes the data and produces a 3D model. I then uploaded that file to <a href="https://sketchfab.com/">Sketchfab</a>.</span><br />

<span style="font-family: inherit;"><span style="color: purple;"><br /></span></span>
<span style="font-family: inherit;">Now that I have the 3D model the next step was to bring it into <a href="http://www.autodesk.com/products/fusion-360/overview">Fusion 360</a>. I thought this step was going to be easy. I was so wrong. </span><br />
<span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;">I first tried importing it just as an OBJ file but Fusion 360 didn't like it. I went online and found different ways to import OBJ files. When I finally got it imported, the CAM part of Fusion 360 didn't work on it. So back with more googling, I found I needed to convert it to a B-REP Surface. </span><span style="font-family: inherit;">The steps I used to accomplish this are:</span><br />
<ol>
<li>Import the OBJ file into <a href="http://remake.autodesk.com/about" style="font-family: inherit;" target="_blank">Autodesk Remake.</a></li>
<li>Decimate the file to less than 30,000 triangles (decimate it to less than 10,000 if you are doing this on a laptop). The number of triangles refers to the number of flat surfaces that make up the curved mesh--it is like the detail level of a 3D printer. (Read more about triangles in models <a href="https://cloud.materialise.com/tools/triangle-reduction">here</a>.) We need to make the number of triangles lower so the model is easier to process. </li>
<li>Export as a OBJ file for Fusion 360.</li>
<li>Import to Fusion 360, using 'insert mesh'</li>
<li>Right click on the mesh, and click 'convert to B-REP'</li>
</ol>
You can read more about how to do <a href="http://talesofa3dprinter.blogspot.com/2016/10/importing-3d-scan-or-stl-into-fusion.html" target="_blank">this here</a>.<br />
<b><br /> STEP 3: Export design for Othermill</b><span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;">Now that it is in Fusion 360, I started the CAM process. CAM stands for Computer Aided Manufacturing, in this context it is telling the othermill how it should mill your part. This is similar to the slicing process for the 3D printer.</span><span style="font-family: inherit;"> This process was arduous because I only decimated it to 25,000 Quads and I was running on my laptop. I finally got fed up and just exported it for the Othermill, but in my haste I forgot to add a finishing process so the first version didn't turn out well. After I had a good night's sleep, I started running it on my desktop which is much faster and has a dedicated GPU. I am not going into much detail on how to use the Othermill with Fusion 360 because they already have a great <a href="https://othermachine.co/support/2d-3d-design/fusion-360/" target="_blank">tutorial</a> on it. </span>I choose the Othermill because it is easy to mill once you have the design and file.<br />
<br />
Now back to the design, I wanted to make little faces of my teacher, I settled on making four of them. I copied the model four times and then moved on to the CAM process. You can view my file here.<br />
For the CAM, I used an Adaptive Clearing tool and a Parallel Tool for the final finish. Next I exported it as a .gcode file for the Othermill and put it into the Othermill software.<br />
<br />
<b>STEP 4: Mill into wax</b><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6Kx5YBdPJw_F4Df0gsXwgO-vRFfczjqVovmxPkUKn4UCe8175Q1WrwXzueV-YVWUZApuvf1OnOQDwKaZpGH9DVNjwkDE1bXQEpgo-WEmDY6DGR9QOPz-Vts5nMqn4z83xFPWm2-iyZ-U/s1600/fast+mr+sanborn+othermill.mp4" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><span style="color: black;"><img border="0" height="150" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6Kx5YBdPJw_F4Df0gsXwgO-vRFfczjqVovmxPkUKn4UCe8175Q1WrwXzueV-YVWUZApuvf1OnOQDwKaZpGH9DVNjwkDE1bXQEpgo-WEmDY6DGR9QOPz-Vts5nMqn4z83xFPWm2-iyZ-U/s200/fast+mr+sanborn+othermill.mp4" width="200" /></span></a><br />
I connected the purple wax to Othermill with Nitto Double Sided Tape (available at <a href="https://othermachine.co/store/fixturing/high-strength-double-sided-tape/">OtherMachine Co</a> or other suppliers). Nitto tape works extremely well, much better than double sided tape. Then I started milling. The milling took 4 hours to complete. I decided on using a 1/16 ball end mill, because 1/16 would give me enough detail, and want it to take more time. 1/16 bits also rarely break unlike smaller sizes.<br />
<br />
<b>STEP 5: Create silicone mold </b><br />

Now it is time to pour the silicon. I use <a href="https://othermachine.co/store/materials/pourable-silicone/">silicone from Other Machine Co</a>, mostly because it is rated as food-grade. I mix the orange and white in equal parts in a cup, then pour it into the mold, I let this set overnight.<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEipSB7ZOKEUW7mHqYG1_9oIX26BRDNx08mhHrQIMxa2t_AczWOmLZFvYnkiGkZCgxZGHiVgArFpgfy8jWWx-B3udNZm1UcWoK1h9MulcbMgEcT0vwQRRUx5egw2PWXon6gWHWWCiFGz2bA/s1600/IMG_20161002_095748.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><span style="color: black;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEipSB7ZOKEUW7mHqYG1_9oIX26BRDNx08mhHrQIMxa2t_AczWOmLZFvYnkiGkZCgxZGHiVgArFpgfy8jWWx-B3udNZm1UcWoK1h9MulcbMgEcT0vwQRRUx5egw2PWXon6gWHWWCiFGz2bA/s320/IMG_20161002_095748.jpg" width="320" /></span></a><br />

STEP 6: Pour chocolate! </b>To melt the chocolate I used a double boiler, and then I used a spoon to take the chocolate and put into the silicone mold. I then put it in the fridge to set. Some tips for if you want to mold chocolate use some parchment paper on the top of the mold to keep it flat.<br />

In particular, I have sought to learn how to use <a href="http://avizo3d.com/" target="_blank">Avizo,</a> which allows much more advanced image processing than FIJI (the open source alternative). One big obstacle was cost: an Avizo license sells for $5000 -- with the education discount. I emailed Avizo and requested -- and received -- a free trial. When I looked online for <a href="https://www.youtube.com/channel/UCjZcPvtwm_Fb3i0FzA1bA-A?&ab_channel=SamSchickler" target="_blank">video tutorials</a> on how to use Avizo, I could only find one or two videos. During the trial, I made several tutorial videos of my own. I then asked Avizo to extend my trial for as long as I continue producing <a href="https://www.youtube.com/channel/UCjZcPvtwm_Fb3i0FzA1bA-A/videos" target="_blank">high-quality tutorials.</a> They agreed and it has been a great partnership.

I first heard the news last week from 3DPi (read their comprehensive article <a href="http://3dprintingindustry.com/2015/03/17/breakthrough-layerless-3d-printing-25-100x-faster-prints/">here</a>). Inspired by the T-1000 from Terminator 2, Dr. Joseph DeSimone and his team have come up with a truly revolutionary idea in 3D printing. Check out this video (at 7x speed). It's so fast, they printed an object (which would take up to 11 hours using traditional 3D printing methods!) DURING the 10 minute <a href="https://youtu.be/ihR9SX7dgRo">TED talk</a>!<br />

<a href="http://carbon3d.com/" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgmhWW-EWMAmoQVltp67aeOHC5WrC6XVqloe5zqlfx3wTLgjdFvC7KDFQ7K3ZuIbH4a8kRv6XPTxxYlqfLc4ZJSAklvdee4zkBAnOXKC43TYd_xmBPUYMH-VurfA42iHD7h3-cDDOtoEGQo/s1600/clip-3D-printing-close-up.jpg" height="200" width="190" /></a>They call it <a href="http://carbon3d.com/">CLIP</a> - Continuous Liquid Interface Production. And it <i>grows</i> parts instead of printing them layer by layer! (more on this later) Take a look at the micrograph (right) - the image on the right is a traditionally 3D printed part with layers, on the left - CLIP! Plus, CLIP is 25-100 times faster than traditional 3D printing.<br />
<br />
Dr. DeSimone, CEO and Co-Founder of <a href="http://carbon3d.com/">Carbon3D</a>, says, “Current 3D printing technology has failed to deliver on its promise to revolutionize manufacturing. Our CLIP technology offers the game-changing speed, consistent mechanical properties and choice of materials required for complex commercial quality parts.” <br />
<br />
So, how does Clip work?<br />
<br />
For now, I'm quoting right off <a href="http://carbon3d.com/">their website</a>, and will add as we learn more. <br />
<br />
<blockquote class="tr_bq">
CLIP is a chemical process that carefully balances light and oxygen to eliminate the mechanical steps and the layers. </blockquote>
<blockquote class="tr_bq">
It works by projecting light through an oxygen-permeable window into a reservoir of UV curable resin. The build platform lifts continuously as the object is grown.</blockquote>
<blockquote class="tr_bq">
The heart of the CLIP process is a special window that is transparent to light and permeable to oxygen, much like a contact lens. </blockquote>
<blockquote class="tr_bq">
By controlling the oxygen flux through the window, CLIP creates a “dead zone” — a thin layer of uncured resin between the window and the object.** </blockquote>
<blockquote class="tr_bq">
This makes it possible to grow without stopping. As a continuous sequence of UV images are projected, the object is drawn from the resin bath. Sophisticated software manages the entire process by controlling the variables. </blockquote>

<span id="goog_2039556059"></span>Our new cube recently started malfunctioning again. We saw that filament was coming out at 1.52mm instead of something closer to .4mm. Luckily we still had our <a href="http://talesofa3dprinter.blogspot.com/2015/01/ou-new-cube-take-3.html">old Cube</a> that we have yet to return (oops) - that one has a malfunctioning control board. Since the extruder on that old Cube still worked we thought why don't we try to replace our new cube's extruder.<br />

We took this project to our after school 6th grade 3D printing club. Where we started, trying to figure out how to get the extruders off. As it turns out the extruder is only attached by 2 screws that we could easily take off. We took off both extruders 1 from each cube 2 and swapped them to create a FrankenCube. We tested it out and it worked.<br />
