Here is a box with the external dimensions of 80 mm x 60 mm x 50 mm. It can be printed easily and without support. I used 25% infill and 3 wall loops. I mainly use it to store my ball bearings, screws, and other small items. 

The bottom part is also available for download with compartments.

2 M3x12 screws are required.

Furthermore, 4 magnets of 3mm x 2mm are needed so that the box closes properly.

If you download it and you like it, please leave a like and a make. If not, don’t hold back with criticism, I’m open to improvements.
