This is a 00 (10mm in center) ear gauge blank. This is just one so it can be sized up in something like fusion 360 or tinkercad. The inside diameter is what determines your gauge size. 00=10mm, the tapered diameter is about 12mm. I got these measurements off of my own gauges. Made gauges with my logo on them, and decided to make a blank one for other people to design their own.
Print in resin, make a mold, make lots of gauges.
