geneva-drive
This experiment creates a working, printable Geneva drive. The Geneva drive is constructed by printing two gears (a drive and a driven gear), a board, and two screws. The screws attach the gears to the board, while allowing the gears to spin around freely.
I actually printed this design, and it works very well!
Rendering
The resulting model (minus the screws) looks like this:
During the debugging stage, I also created a rendering of the gear profiles:
The program also produces an animated GIF of the Geneva drive in operation. However, it is not included here to save space.
