A friend of mine was interested in a beautiful copper book holder ring on Etsy but it's a bunch of money. So I designed one for them!

Prints in PLA or PETG without issues, however PETG is recommended as it's much harder to break. But it's a quick print, so go for it whatever material you have!

“Holy sh*t, that bookmark works great!” says my partner. (They did not expect it to)

I tried to print it in TPU as it's really strong but that was a floppy mess.

I've included the OpenSCAD file so you can tweak it's size a bit. You want to use the nightly release and enable Manifold if you want it to render fast. I've been playing with adding a logo, but it does not print well (yet).
