A radial bearing toy that can be customized to any size, with any amount of bearings. It can be scaled up to be a bracelet or just stay the same size to play with. This is my first parametric thing so let me know how it works out. The "Radial Bearing" stl has a support ring for the bearings so support shouldn't be needed. EDIT: I modified the SCAD file so that now it is better optimized for larger bearing tolerances, heights that are less than the fillet and added a third type of support that supports the individual bearings.Remove support ring and make sure all bearings can turn freely. It should become easier to turn the more its worked. When scaling to larger sizes, make sure that there are a lot of bearings so they will keep the center in and not fall out.
