When I first downloaded these files the size was teeny-tiny and the images were mirrored so "Bookmarks" was backwards for some reason. It could have been my software that made it that way. I flipped them, made them larger, and added "Bookmarks" to the front covers. It looks super cute holding bookmarks for the 3D printing classes we offer at our library :) I found they print best with supports to account for the overhang on the spine and pages of the book.
I also included a file without the bookend portion of the image in case you just want it out on your desk like we have it. This print does not require any supports.
