This box prints without supports. The hinge is designed around a 0.125" pin, however that can be changed easily in the model to use a piece of filament, nail, ect.

There are holes to glue 0.125" diameter by 3/16" long magnets into the top and bottom to help hold the box closed. These are not required, but nice to have if carrying the box around.

I printed mine in grey Prusament PETG.
