I made it for my GoPro Hero 9, but considering most action cameras are smaller, you could just use some thicker sponge or scale it down.

The drawer is big enough to fit some adaptors and the other compartment fits a small charging cable.

Tested in PLA at 0.2 layer height and it works pretty well.

The lid is intended to be opened from the side with only one latch first.

LE: Simple versions for the lid and body added.
