In search of a gift to print, I found many smoker's rings on this site, but upon printing, they were found to be very flimsy and very utilitarian. Since it would only require a few shapes, I decided to make my own, and this was the result. I feel that it is stronger and more comfortable than the others I have found.

The inside diameter is roughly 16mm, so it is quite small. I may make a larger one later.
