For the hinges you need 1.4mm thick nails.
I've had them lying around, idk how common they are. Mine are 25mm long, thats a bit too long, so i snapped a few mm off.
I printed the case with Bambulab PLA-CF, only the hooks are printed from PETG because they have to be a bit more flexible. The hooks and the “blocks” have to be superglued into the hatches.
