If you have never heard of printcraft, it is a creative server for minecraft. Minecraft is a sandbox game where you break and place blocks of various materials. Printcraft is one of the many ways that players of minecraft can create an STL file of the things they create. This means they can physically print the things they create in the game. What makes printcraft different is that it converts the standard minecraft block, 1mx1mx1m, into a 2mmx2mmx2mm block when creating the STL file. This means that you can build things to scale and for specific purposes. While it is still used primarily by players who want physical copies of their favorite game elements, it is an excellent way to introduce youth to the idea of designing real world objects in 3D. So far I have printed new usb drive cases, have drawn a holder for my tv remote controls, and printed a Tardis that my 14 year old son drew.
