You can 3D print all of the parts for this project. Here is a list to help you keep track:
- Main enclosure - 1x
- Bottom lid - 1x
- Sun gear - 1x
- Planet gears - 3x
- Dreidels - 3x
- Gear carrier - 1x
- Stepper motor mount - 1x
- Electronics mount - 1x
- Disk cover - 1x
The files can be downloaded directly below or from Printables. The files are available as .STL files or compiled .3MF files that include multicolor info, multiple copies of the model if needed and printing settings.
The source file is also available as both a Fusion360 project file and .STEP file.
The Hebrew letters on the dreidels and enclosure can be printed with a contrasting color for printers that can do multicolor printing. They are designed with a 45° chamfer around the edges so that they print cleanly.
Modeling Gears
Modeling gears can be tricky. I followed along with this YouTube video to get the gear system in place. It goes into great detail on the math you use to create these gear systems.
