Geneva Mechanism

The Geneva Mechanism designed by Angus from Makers Muse, I modified it to be fully 3D printable, no hardware required, although some sanding might help it run smoother.

The Geneva mechanism an elegant way to translate continuous rotation into intermittent motion. It’s classically used for movie projectors and is responsible for that iconic sound they make. It’s also used occasionally for indexable machines and CNC tool changing, and in some mechanical watches.

(Note: I changed the crank after test printing, so it should fit better and be easier to use)
