Ring - 2 Piece Helix

These fun rings print in 2 pieces. You twist them together! Combine colors. With a little sanding after printing they feel more comfortable to wear.
The stl I have provided prints at about 23mm outside dia. Or 21mm inside dia. That is around a size 11 I believe. I scaled it down to fit on my girls.
I made and printed these last year, so if you print one, please tell me the dimensions and I'll update this description.
This was inspired by a Paul van Doorenmalen design. Check out his stuf
