I couldn't find a ring holder that didn't also hold other rings like necklaces and bracelets. Most of them took up a good bit of space that the husband and I just do not have on our bathroom countertops, so I made me own!

Low profile, minimalistic, very easy to print, and holds at least 2 rings.

Can be printed in one solid color, but I did a M600 layer color swap for a small accent line, which is totally not needed. 

Can be printed with PLA or PETG, there is no reason why PLA would not work.
