This is a simple glasses case.

The outer parts are printed with the fuzzy option of Cura, this creates this rough, glittery surface.

Outer parts and lock: PETG or ABS, printet with the fuzzy setting from Cura, Density 40%
Top part with support, all others without.

Glasses symbol: PLA, ironing enabled, no fuzzy setting

Inner parts: TPU95, Density 20-30%, no fuzzy setting

Notes:

My case fell on the hard floor :( and the hinge partially broke.
Apparently PLA is too brittle for these, so I recommend PETG or ABS for the outer shell.

After printing: Hinges bored out with 2 mm.
To connect the hinges, push a piece of PLA filament (1.75mm) through each, carefully melt the ends.

Glue the inner parts made of TPU95 into the outer parts.
