Screw terminal box

I made a screw terminal box based on my previous thing:

No holes here, but you can add anything you like on OpenScad.
So you might drill it as you need. (I cannot made 50 versions here, for every diameter)

I upload two version here:
- one with a strong back structure
- one with bigger space but weaker back surface.

The size of the case is 6cmX8cmX2cm (little bit bigger in my case, but I think my 3D printer is to blame)
The closed box is 2,2cm with the lid.
