About this 3D model

This is my entry for the Develop3D robot design contest. I've been wanting to make a modular robot for some time now, and I figured this was as good a way as any to start! With the pins, he should snap together without any glue, and the ball joints should function a bit. So, here's the link to my TinkerCAD model: https://tinkercad.com/things/187wSn06BB4-modulo I'd like to put it out there for all of you Thingiversers to add parts for Modulo should the inspiration take you. Post up anything you make and if it fits him, I'll add the stl to his downloads. Drill arm? Jet pack? Crawler legs? More poseable bits? Any takers? -Arian
