Geneva Drive Model

My friend Pete shared the animated GIF attatched to this thing and said "this has RepRap written all over it", so I decided I had to model it and print it.

This is a model of a Geneva Drive, which converts continuous rotational motion to intermittent continuous motion.. (think of the seconds hand on a clock which "ticks" rather than moving smoothly).
