This week’s geek craft is Mario Turtle Shell Racers made with a 3D printer.

A motion sensor on the blue one would help it track people down.

These things are seriously awesome (as are many of the projects over at Thingiverse), and they have extremely detailed instructions on how to make them yourself. The big drawback is that if you want to make one of these you’ll need a 3D printer. C’est la vie.
