Mineways : 3D Print Your Minecraft Model

Mineways is a free program that makes it easy to select a model from a Minecraft world map and render it and 3D print via Shapeways.

Developed by Eric Haines, the latest version of Mineways runs on Windows (or Linux under Wine) and allows you to output Minecraft models in full color, or to fabricate in plastic.  Check out Eric's Mineways Shapeways Shop for examples or the Mineways Flickr group he has set up.
