Geneva Drive

This is a recreation of the Geneva drive, a strange geared mechanism used in many applications from CNC tool changes to old film projectors. It is a fun and easy print without the need for support that can be used to fidget with, showcase 3d printing, or as an interesting desk toy/paperweight. Print with 0.2 mm layer height. I have provided both the pre-oriented plates ready to print and the individual part files. Enjoy!

ASSEMBLY:

1. Take the drive gear with the pin and place it upon the rear case, as shown.

2. Place the 6-sided driven gear on top of the second hole, with its spacer on the bottom.

3. Insert the cylindrical axle into the driven gear that was placed in the last step. Ensure that it is pushed through both the gear and the hole in the case.

4. Attach the front case by inserting the rectangular pins into the holes on the edge of the rear case. Feel free to add glue if necessary to hold the parts together.

5. Finally, attach the drive gear axle with the handle into the drive gear, making sure that the flat faces align and that it is pressed through the holes in all three parts.

Your Geneva Drive is now finished and ready to be used! Simple rotate the three-pronged handle and you're good to go.
