I created this for my wife's crocheting hobby so her pointer finger that helps keep tension wouldn't get raw from the yarn sliding over it. The ring size is a 8.5 (18.54mm) however it can be scaled apropriatly to fit any ring size. Hope this helps someone else!
Update: I have included more ring sizes so scaling may not be required.
