The entire gear system is 3D printed.
But the following parts will be required for a smoother operation.
All listed parts are from McMaster-Carr but are available in most specialized shops:
- 1x Stepper motor NEMA 17: 6627T64
- 4x Ball bearing 686-2RS: 4668K231
- 1x Ball bearing 7201-2RS: 6680K35
- 4x M2.5 Screw, 22 mm Long: 91292A312
- 4x M2.5 Washer: 91100A110
- 4x M2.5 Hex nut: 90591A270
What is not listed above is the controller (could be an Arduino or esp32), and the stepper motor driver.
You can easily find a stepper driver breakout board. This makes the wiring much easier!
The original F3D file can be found in the files list.
Since it is controlled by a stepper motor, you can define the speed and movement curve.
Note that you will need 4x Helical_Radial_PlanetGear for this project.
You can find my full course on how to make your own directly on my Instructable page!
