This is a box with 2x4 compartments openable by a rotation.

Really easy to print.

The dimensions are 10 x 10 cm (5 x 5 for each compartments).

Be gentle when closing it, it needs no force, if it's blocking when closing just go back and close slowly and it will work ;)
The nut has to be loose but tight enough. And it works better horizontaly.

Printing settings:

Supports: no
Resolution : 0.2 mm
Infill: 10% (but 15% for the base and 3 walls)
Filament material: PLA
