The Geneva Drive is an elegant mechanism used to convert rotary motion into intermittent motion. Click on the image above to view a video of the drive in action on my Instagram feed. I’ve designed the part for this project in Autodesk Fusion 360. If you have access to a 3D printer you can follow these construction instructions to make your own 3D printed Geneva Drive.
They should be suitable for most 3D printers.
Here are the five parts ready for assembly.You will also need some cyano glue a small screw and a washer.
A dot of cyano glue holds the handle and crank together.
Thread the crank through the hole in the base.
Fit the drive wheel to the crank. A dot of cyano holds the drive wheel onto place. Make sure that it turns freely.
Fit the Geneva wheel over the pin on the base so that it lines up with the drive wheel as shown.
A small screw and washer holds the Geneva wheel into place. Don’t over tighten it as the wheel needs to be able to turn freely.
That’s it! Your completed Geneva Drive.
