Planetary gear fidget spinner

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 librari
