Page Holder Bookmark Ring

thingiverse

I'm designing a compact bookmark that doubles as a page holder, perfect for those who prefer to read one-handed while lounging lazily. The added holes on the ring enable you to clip a pen in place, and the top hole is designed for attaching a ribbon or an accessory. The ring's diameter was carefully crafted to fit comfortably around my thumb. Update 2/21/2018: I've created V4 without a spine for added convenience.
