Parametric Thrust Bearing Retention Ring (works with Airsoft pellets)
thingiverse
This scad will generate a ball bearing retention ring of any size you desire with any number of balls! I created it to work with Airsoft pellets (BBs) but it will function perfectly with any ball or sphere-shaped object. The idea is to utilize 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 great about that second function is that you can now create 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 them together. https://youtu.be/j6dzyoloH88 See it in action in my forthcoming Universal Hangable Auto-Rewind Spool Holder: https://youtu.be/Bc92DEOSwZQ **EDIT:** I've updated the .scad with lots of comments, a version string, and a changelog. That's all that has changed. I've also renamed the Thing to indicate this is for thrust bearings (not roller/ball aka skate-style bearings). **EDIT 2:** I've added an example of a thrust bearing that would use one of these retention rings.
