Digital Orrery
This is a project to create a digital orrery, each planet can be addressed and controlled individually.
Parts list
- 4x Nema 17 stepper motors, 40mm: https://www.amazon.com/gp/product/B00PNEQI7W
- An Arduino Uno
- Arduino CNC shield: https://www.amazon.com/gp/product/B06XJKVLG3
- All of the 3D printed parts
Printing
All the parts will need to be rotated because Fusion 360 likes to output STL files in the wrong orientation. I printed all parts at 0.32mm and they work pretty well, so I don't think a finer resolution is required. However, it would probably be wise to sand anything that slides around, mainly the inside and outside of the shafts.
Print one of ever part, and 3 of the sun pins.
For the collars, drill a hole into them around the middle of the protrusion for whatever wire you are using to hold the planets. The collars should snap firmly onto the shafts, I did not use glue.
