The hinges are designed with a 2mm hole so a length of standard filament can be used as a hinge pin.

Printed on a Creality Ender-3 v2

I didn't use rafts, but if warping is an issue, feel free.

For the hinges and latch, supports are recommended. I used Tree.

Infill of 20% minimum gives a reasonably strong case.

I used IIIDMax PLA+ filament.

The case halves are small enough to fit two on the Ender 3 bed for simultaneous printing.
