I was inspired by a few similar boxes I found online, so I redesigned one in my own way.

The box dimensions are 120 × 70 × 60 mm (internal dimensions: 116 × 66 × 56 mm).
I will upload more size options later.

Assembly:

• Screws:
  1. You will need six screws (DIN 912 M3 × 30 mm).
  2. The screws create their own threads as they are screwed in, so no prior threading is necessary.
• Stacking:
  1. The box and lid have slotted holes designed for printed slotted pins, allowing multiple boxes to be stacked securely.
  2. The pins snap into the lid with slight pressure.
  3. This feature is optional - use it only if you want to stack multiple boxes.

Printing:

• It is recommended to apply a glue stick when printing the latch and pin, as their contact area with the print bed is relatively small.
• For a textured finish, print the lid on a textured sheet to achieve a rough surface on top.
