Spine Bookmark V1

thingiverse

I remixed this from a corner bookmark to actually slide over the spine, instead of the page corner. For very large hardcover books you might need to adjust the width of the gap to allow the spine to fit into it, but so far I've had some pretty sizeable books work fine with the allocated space. What's nice is that you can add multiple bookmarks in the same volume, to help with study, and they still look tidy.I have now added V3 because the first couple were too thin and tend to rip. I've also made it a bit longer. Still a work in progress.
