An easy way to save your page on a book you're reading! Barely uses any filament and doesn't take long to print. Bookmark can be printed in PLA, as it is super flexible, just don't bend it too much. You can customize the letter at the top of the bookmark and indent letters on the bookmark(Tinkercad is probably the easiest to do this on). To hook the bookmark, simply push the page(s) between the arrow and the two lines.
