I remixed TheSameNameTwice's Bit Storage Frog Box for some extra space and because I didn't need so many bits.

I used PrusaSlicer's awesome “Negative Volume” for it. That's why I added the 3MF here. All parts are original but modified in the slicer. So if you're searching for the parts check out TheSameNameTwice's design.

To open the latch, just press the small "button" and the latch pops open.

It must be printed in the same orientation as the STL files were exported to the 3MF.
The hinge is a 1.75mm filament piece.

You can either put the parts together with a M3 x 25 mm screw with a M3 nut (total of 8 screws and 8 nuts) or thread 2 M3 x 10 mm screws from each side. (Total of 16 screws)
