I updated this model to be smoother and add several sizes corresponding with the ring diameters.

Inside ring diameters:
Ring size 3 - 14.1 mm
Ring size 4 - 14.9 mm
Ring size 5 - 15.7 mm
Ring size 6 - 16.5 mm
Ring size 7 - 17.3 mm
Ring size 8 - 18.1 mm
Ring size 9 - 18.9 mm
Ring size 10 - 19.8 mm
Ring size 11 - 20.6 mm
Ring size 12 - 21.4 mm
Ring size 13 - 22.2 mm

Stand size: 
height varies from 98.4 to 108.8 mm
diameter varies from 45 to 55 mm

There is nothing to say. It is easy to print. Enjoy.
