Planetary gear fidget spinner

thingiverse

This is a funcational planetary gear system comprised of 24T gears at 20 degree pressure angle with a 20 diametral pitch. To put this together, you'll need the following additional materials: (4x) 626-2RS bearings (3x) 6mm x 20mm bolt (1x) 6mm x 30mm bolt (4x) 6mm nut The arm assembly has a very small (0.5mm) lip on one side which secures the bearing in place. If you find you cannot press the bearing down, try flipping it over :) For each file, the number at the end represents how many of that item you must print. For example, spacer-x4.stl means you should duplicate spacer 4 times. NOTE: To run the OpenSCAD files there are some things to mention. First, you need OpenSCAD beta version from October 2019 or later so that you can enable the function-literal settings. Once you've downloaded the beta version, you can... Go to Preferences -> Features -> function-literals Next, you'll need to add `gears.scad` as a library by copying that file to your openSCAD libraries folder. Also consider adding `openfusion.scad` as a library too. Then you should be able to run any of the other files.
