Case for folding headphones Koss Porta Pro.
To protect headphones from scratches i glued two foam circles on the top and the bottom of the case.
The monkey shape is from Nazca Lines in Peru.
I used "adaptive layers" in Cura to get fine layers on the threads and to save some time on the rest. It's about 0.12mm for the threads and up to 0.28 for the walls.
