3D Printed Geneva Drive


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.geneva-a15 I’ve designed the part for this project in Autodesk Fusion 360. If you have access to a 3D you can follow these construction instructions to make your own 3D printed Geneva Drive.

Download the STL files from the link above. They should be suitable for most 3D printers.

I printed the parts out in a variety of colours of PLA from rigid.ink using an Ultimaker 2.

Here are the five parts ready for assembly.You will also need some cyano glue a small screw and a washer.

geneva-a07A dot of cyano glue holds the handle and crank together.

geneva-a08Thread the crank through the hole in the base.

geneva-a09Fit the drive wheel to the crank. A dot of cyano holds the drive wheel onto place. Make sure that it turns freely.

geneva-a10Fit the Geneva wheel over the pin on the base so that it lines up with the drive wheel as shown.

geneva-a11A 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.

geneva-a12That’s it! Your completed Geneva Drive.
