Bonjour, mon français est terrible, mais merci pour un travail aussi merveilleux.

I have a question as to how to add a hole in the top or bottom plate. I played with the code and I see that I can add a cylinder at position 50, 50 with the code below, but what I really want is a hole at position 50,50 of radius 10/2. I'd like to add this so I can mount the box and just drilling a hole seems far too easy

difference(){// hole
' #translate([50, 50, -2]) cylinder(r=10/2,h=6);

Thanks again for your time and effort with this project. It's wonderful.

Update for others:

In openscad, where the code is placed is import too. I resolved my issue by simply moving my translate code down to the end of the script
