Spacer for fidget spinner

thingiverse

A versatile adapter for fidget spinners employs 608zz skateboard bearings, allowing users to substitute 5/16 hex nuts for added weight. This approach optimizes bearing utilization and enhances overall spinning performance, as spinners appear to spin more smoothly and rapidly. To assemble the adapter, print it at a 100% scale using a vice to secure the bearings in place. I deliberately designed this adapter to be easily removable from fidget spinners, enabling users to seamlessly switch between bearings or replace them entirely. A moderate infill setting of 20% is recommended, accompanied by 2-3 top and bottom layers, as well as 2 or more perimeters for optimal results.
