Yet another box you can modify as you need. I included the Fusion file and a STEP file.

You can change using parametres:

• Length, Width and Height
• wallthickness, bottom and lid thickness
• Rib factor (default 1 as in the pictures) but can be 2, 3, 4 or more
• Bolt diametre and length (default M3x35) for the hinges
• Champfer and Fillet diametres (be carefull, can easily be to big)

I included some different sizes for you all to print and use.
