From my file vault is this funky little Soviet machine, the SMZ Cycle-Car. I found this model and I had to have it for my shop collection, now YOU can make one too! I didn't draw it up, I just converted it to STL and scaled it up some.
Be sure to stop by the original artists page and check out this one, and all the other cool stuff there!
