My son wanted a creeper bookmark, and despite there being many to choose from, did not like any that were readily available for printing. I made this design with a head slightly larger than the top of the bookmark. It is designed to be printed in 1-3 colors. The main bookmark is 1mm thick. The head is 1.2mm thick. The facial features are 2mm thick (the height gives it some depth. If you set a filament switch at specific layers, you should have no problem achieving the appropriate effect.
