I couldn't find an earbud case design I liked so I created my own.
Print the sliding cover scaled at 99% if you don't like sanding.
You can attach the emblem on the cover with glue. "Hole_covers.stl" is not needed for using the case. It is only cosmetic.
Added a case with 1,6 mm walls instead of the original 2 mm: brings print time drastically down with 0,4mm nozzle.
Doesn't matter PLA
