print in place spinner ring

The ring boasts an ID of 22mm, which is the actual finger measurement. I've also included a curve file that you can import into your modeling program to revolve and create a ring of the desired size. Once printed, complete any post-processing as needed, such as sanding and removal of the support flare at the bottom. When shaping the join between the inner and outer rings, use a blade carefully to persuade it into place, as it may require some initial coaxing before spinning smoothly. The clearance between the two rings varies from approximately 0.25mm to 0.35mm.
