Yet Another (But Less Cumbersome) Book Ring

Book ring with less bulky design than some of the ones I've seen. Use original size for adult men, scaled to 85 % for adult women, or scale as needed.

No supports needed, any material will do, print in wood-fill or stone-feel for the extra tactile pleasure.

No

Supports:

No

Resolution: 

100-200um

Notes:

Make the wall thickness a bit bigger than usually for extra mechanical strength (2mm seems a good value). Print in wood-fill or stone-feel for the extra tactile pleasure.
