Masonic Stud Earring

I had a stud earring with square and compass. Because of its sharp tips it often hanged in fabric while undressing or in a blanket ... and one day it was gone.
The I decided to design one with a circular base - without the tips and edges.

I printed mine 7 mm wide and 2 mm thick in resin.
I casted it in silver using green sand. Then I soldered a pin to it.
