Planetary fidget spinner
Description
Low friction design with sufficient play to run very easily, just like a fidget spinner. It doesn´t require any additional parts such as bearings and prints as one part. I play with this a lot while working on my PC, it´s kind of relaxing. Gear data: Modulus: 2mm, Pressure angle: 40 degrees, Helix angle: 40 degrees, Height: 16mm Teeth: 30, 10, 10 (I created this using a home-made parametric solution in Fusion 360, not a plug-in) The sun gear tightly fits a 8mm hex key. If you scale it down (50% shown on photo) you might want to reduce the horizontal expansion in your slicer tool to adjust the gaps and ensure smooth running. UPDATE (February 2, 2021): Finger rest added. Print 2 and plug them in for more comfortable spinning. HAVE FUN and consider sharing your make with the community!
