Parametric Thrust Bearing Retention Ring (works with Airsoft pellets)
Description
This .scad will generate a ball bearing retention ring of any size you want with any number of balls! I created it to work with Airsoft pellets (BBs) but it will work with any ball or sphere shaped object. The idea is to use this in a "race" (track above and below balls being held by the retention ring) or as a spacer inside of a regular bearing. What's nice about that second function is that you can now make *really great bearings* of just about any size by merely modeling the top and bottom rings in such a way as to snap together (or glue together). https://youtu.be/j6dzyoloH88 See it in action in my (forthcoming) Universal Hangable Auto-Rewind Spool Holder: https://youtu.be/Bc92DEOSwZQ **EDIT:** Updated the .scad with lots of comments, a version string, and a changelog. Other than that it's the same. Also renamed the Thing to indicate this is for thrust bearings (not roller/ball aka skate-style bearings). **EDIT 2:** Added an example of a thrust bearing that would use one of these retention rings.
