I started to learn how to make bookmarks, and while still using hueforge. There is a negative shape in the print that allows for a hole on the top to put a tassle. It can be removed before slicing if you don't need it.

Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm

The Model is 50.11x200mm in size
You may print at higher layer heights below the Min Depth of 0.64mm
The Max Depth is 2.2mm and the Actual Depth is 1.8mm

Filaments Used:
PLA Overture Matte Black Transmission Distance: 0.1
