This is a double-hinged folding case for storing UNO!™ playing cards (and possibly other cards of the same dimensions).

The internal storage volume is 55.75mm × 87mm × 30mm (plus some clearance). It requires 2× hinge pins 92mm in length and 1mm in diameter. I have added a v2 that uses 1.75mm filament as the hinge pin as well as improving the latch strength.

Print each piece on edge with hinge hole aligned vertically and, for the top and bottom, the end portion sitting flat.

Designed with 0.4mm print nozzle in mind.
