In Germany we have a new special edition of the IDW Teenage Mutant Ninja Turtles coming out (you should check it out if you're from a German speaking country) so I needed some bookmarks.

First of all, credit where it is due, I found this awesome vector design:

which I used as a basis in Illustrator to cut out some flabby flaps, extruded the parts 0.2 mm and voila.

I made one 3mf for all the 4 vectors of the original design, but I think for a classical feeling you can just print the Michelangelo one in all colors.

Printing

I printed mine in 3 layer thickness with 0,2 mm each; if you make it 1 or 2 layers it will be less thick and maybe cramp your pages less, but I think 3 is good.

Please be careful, the 3mf files are only 0,2 mm high, so please adjust the Z height in your slicer accordingly
