Very Happy Robot is now on Thingiverse!
So far I have uploaded two things I designed: a 3/4 sun that I used on my recent science fair project poster board, and a small 2 x 2 x 2 cm calibration box for the printer. I designed both of these files using 123d Design (an easy-to-use free 3D designing app).
Thingiverse is a CnC, Lasercutting, and 3D printing file sharing site, started by Makerbot. The files are for anybody to download and use.
