Planetary gear fidget spinner

thingiverse

This is a fully functional planetary gear system consisting of 24T gears with a 20-degree pressure angle and a 20 diametral pitch. To put this together, you will need the following additional materials: * Four 626-2RS bearings * Three 6mm x 20mm bolts * One 6mm x 30mm bolt * Four 6mm nuts The arm assembly has a small lip on one side that secures the bearing in place. If you cannot press the bearing down, try flipping it over. For each file, the number at the end represents how many of that item to print. For example, spacer-x4.stl means you should duplicate spacer four times. To run the OpenSCAD files, there are a few things to consider: First, you need OpenSCAD beta version from October 2019 or later to enable function-literal settings. Once you have downloaded the beta version, go to Preferences -> Features -> function-literals. Next, add 'gears.scad' as a library by copying that file to your openSCAD libraries folder. Consider adding 'openfusion.scad' as a library too. Then, you should be able to run any of the other files.
