Set of Ring Sizers

Abstract

I had temporarily misplaced my fancy steel ring sizers. Then I found a model online that frustrated me, so I designed these in TinkerCAD.

This includes US sizes 2 thru 15 with half-sizes in-between.

Each model is printed separately and the large master ring is riveted together with 1.75mm filament rivet melted on each side.

The torus rings are all a bit faceted, so I may go back and increase the number of sides at some point. But the faceting doesn't seem to affect their accuracy too much.

There is a bit of shrinkage and inaccuracy involved but the most-used central sizes are the most accurate rings. I did include an .obj file for the size 8 for those that wish to experiment with the parts in TinkerCAD.
