Fidget Spinner "Bearing"

myminifactory

This is an "adapter" for fidget spinners. It was designed to be the same size as the 608 adapters commonly used in fidget spinners. The central hole is 8mm, so you can still use thumb pads easily. The outer diameter is 22mm and therefore should fit into any spinner you might want to insert it into. Lastly, this "adapter" is 7mm tall. There are three different versions available. A loose version (called "adapter") for printers that cannot handle tight tolerances, a tighter version ("adapter-tighter") for printers that can handle tight tolerances, and a version with 4 cutouts ("adapter-slots") based on the loose version but with cutaways to try and reduce friction for a better spin. There is always room for improvement so your comments are welcome. Video: https://youtu.be/UMClVU6S02A
