Wedding Ring
I work at an industrial facility. Sometimes I do electrical work. We are not allowed to wear metal jewelry. Instead of going out and buying a silicone ring, I printed this in TPU.
I do not have a size for this (I am guessing it is a 10 US). Being it prints quickly, guess your size and then scale it up or down as necessary.
Printing a ring is also helpful if you have put on a few pounds (kg's for those who use them) since being married.
