This can be printed in 4 colors, as is shown in the photos.  Prusa slicer makes it very easy to set up the different colors.  Or print it in one color.  The base that fits over the pages is printed with support and opens easily.

If you would like a similar bookmark with one or two fingers pointing, please let me know in the comments.

You can place the book mark on the side of the page and indicate where you stopped reading.
