I used Mineways to export a chunk of a minecraft world, and print it. The model I printed is attached to this thing.Here's a video that explains the process. http://www.youtube.com/watch?v=K3Un7uCm3JgEdit: I've written a detailed tutorial on how to export models suitable for home 3d-printing with Mineways. It's located on my blog, here: http://repraprip.blogspot.com/2012/01/tutorial-printing-from-minecraft-with.htmlPlease share the models you export and tag them with "Mineways". :)
