Ring Sizing Mandrel and Gauge Rings (US size 4-14)

This tool will help determine the size of a ring.  The accompanying OpenSCAD code can be used to generate other sizes and ring models for testing.  The sample gauge rings include a debossed number on the inside of the band to denote the ring's US size (to aid in finding the correct size).

You can store a full complement of rings on the ring mandrel holder.
