(A game that lets you create in a pixelated sandbox type of world)
Step 0: Have your minecraft creation ready in one of your worlds, and move your character as close as you can to it if possible.
Step 1: Go to the Mineways site and download the program for Mac or PC. It's free.
Step 2: Run the Mineways application and click File > Open World > the single player world with what you want to print.
Step 3: Right-Click and drag a selection for the size of the file you wish to export.
Step 4: File > Export for whichever you like.
Step 5: Save the file and set your options.
Your model is saved! Print it.
There's also Printcraft, which allows you to create something in minecraft with a 40 by 40 square. When you push a button in minecraft, the command block behind it sends a signal to their website, which in turn translates your minecraft creation into a .stl file to download. It's entirely free and easy to use, all you need is the ip, (us1.printcraft.org) and a minecraft account, which is about $27 dollars right now.
