Spinner Fidget Ring without supports

I don't have the option of printing with solulable materials and I figured you could probably do this thing in three parts and just glue two of them together. This allowed me to make the parts sit together tighter and in the end, have the spinner move more evenly and smoothly.

The three parts are called Ring_inner (the base), Ring_inner_top (the part that glues to Ring_inner to lock in the spinner) and Ring_outer (spinner). Compared to the original model I've decreased the margins between the top and bottom of the spinner and the base (called Ring_outer.stl and Ring_inner). I've also given the spinner a narrower radius.

The inner diameter of the ring is 20mm.
