Fang Ring
It's vampire fangs on a ring for my dad
I used other Thingiverse models for both basic components:

*Edit: I just came back after printing it and made some small changes, reducing the gap between the back of the teeth and the ring, and smoothing out the back and sides. Not anything cosmetic except what got shifted around slightly.
I printed it in resin and it came out great. The size of this ring is 9 by default, I believe? So make sure to scale it if you want a different size.
