Update 14.12.2022 Made adjustments in design and created sizes from 16mm to 22mm Additionally created a tool that can be used to check correct size if you are making more than one for yourself.

Any tips are appreciated if you like my design. Also please comment if you have any input.

Update. I have added v2 for book rings, with rounded edges for the finger hole.

Hi all,

This is my version of book ring, I have included three different thumb sizes, 22mm, 19mm, 16mm. I use 22mm and my wife prefers 19, so depends on how it fits you. No supports required, print on side.

Main reason for this version is to have all edges that touch paper rounded up, as the previous one that I have downloaded sometimes created scratches on paper. With this one I had no issue so far.

Please leave a comment if you've printed it and let me know of outcome.

Tips appreciated, as they help me develop more designs.
