Geneva gear

After seeing the Makers Muse video on the Geneva gear, my son was inspired to draw up one of his own in Fusion360. It runs quite smoothly, and he enjoys hooking it up to electric motors with a rubber band to really get it spinning, but I find it satisfying to just to spin it with my finger. it requires a metal post to run on, which in this case is just a couple of M3 bolts which should thread right into the plastic.
