Hi,
I have been trying for hours to create a rectangular cut-out for a USB connector in the enclosure wall.
I watched the tutorials, but found them very complex. I tried to understand how the ‘difference’ and ‘minkowski’ functions work. Unfortunately, I have to admit that I didn't understand how they work.
I looked at various examples on the Internet and tried to implement them. Unfortunately without success. The code, I’m using is from a Github repository.
It would be very nice if someone could tell me what I need to change in the source code to get the rectangle cut-out. It is the red rectangle. The source code is attached.
Thank you very much
Peter

you need to create difference from the main module it seems.
Attached is the revised code

Do you understand "scope" The first "statement" defines a shape,
subsequent lines in the same scope within a {} pair are statements
following the same rules but defining what is to be subtracted from the
initial statement. For that initial shape, complex structures can be
built by putting them in a union() after the difference() statement.
I looked at various examples on the Internet and tried to implement them. Unfortunately without success. The code, I’m using is from a Github repository.

I would round the corners of the hole to avoid cracking:
Replace
//cube([5,13,5]);
with
rotate([0, 90, 0])
linear_extrude(5)
offset(1)
square([5,13]);

There are some tricks to make life easier:
I use a structure:
difference()
{
union()
{
// define things here as base object
}
union()
{
// define things here as objects to be subtracted from base object
}
}
The way difference works is that the first object (union, here, and
anything in that union) is the base, everything else gets subtracted
from it. the second union contains objects to be subtracted.
Generally, you'll have a difficult time positioning those objects,
orientation, position, etc. The trick is to comment out the
difference(). That simply gives you the base object and the objects to
be subtracted as objects. I generally color them all red for
visibility. You can easily see where everything is. Uncommenting the
difference() shows you the effect.
