This is a spinning ring, inspired by AmazingSpanoMan's "Customizable Fidget Spinner Ring".

I liked his design, but I wanted to add some constraints:

• It should be look like a regular ring, thin and discreet enough for daily wear,
• There should be no exposed ridges that would rub against adjacent fingers,
• The bearing should seem to fit tightly, but
• It should still spin freely (after wearing down imperfections in the print).

I also wanted to add a tree design for Christmas. This design fills those requirements.

I've been wearing one for a few weeks, and it's been a real hit!

I have successfully printed this ring from 14mm to 22mm diameter (US size 3 - 12 3/4) at 8 or 9 mm (axial) thickness. Going larger shouldn't be a problem, although the smallest rings are difficult to assemble.

If you don't want any trees on your ring, just set the "Number of Trees" to 0. (Or wait for me to publish the "No Design" version.)

Give it a try!
