Box, with an hinge that does not protrude from the back of the box, and a latch.
This box is another take on a hinge box. The hinges doesn't protrude from the box, but the sides needs double walls. When opened, 2 sides are opening, improving access inside the box. An optional latch is included, based on a mechanical switch and a 3D printed button. The latch is one-way: the box can be closed freely (this side of the button is angled, and totally smooth since it's the printing bed surface), but can't be inadvertently opened.
