Yeah i was trying the same the other day, what a nightmare . I would have thought they would have come up with a solution for perfect placement
There is a solution for perfect placement - draw your modifier geometry for the whole part in your CAD program and save it as a separate shape.
In Studio, right click your handle, add modifier, select “load” and load your modifier geometry.
Then, you’re going to position both your part and your modifier geometry using the “move” command, this allows you to locate them precisely. If you set up your coordinates in the CAD model properly, you can select “object coordinates” to make this easy.

This photo is great, support only generates on empty space, so that object might be exported correctly, and it looks like it does want to be a cavity inside.
You can see the outer/inner walls on both sides of the cavity as well.
So disable supports and let it be empty and see what ya get? Top might be droopy unless you have real good bridge settings but maybe that’s tomorrow’s problem
Maybe it best to help us understand what fits into that cavity though. Is it meant to be open from the top, or only through the internal holes? Do you just need to poke out the bottoms so the “clamped” item/handle can continue on past this bracket to a hinge or something?
I ended up away from computer so I may be too late to illustrate what I was trying to describe, but I will still post this anyway.
Above: Two “cubes”. The one on the left is made of two shells mirrored and stacked, the one on the right is a solid cube.
Above: Both parts sliced with only one wall. Note that the infill to the hollow shell is only where I put the walls of the object.
Above: Using a modifier cube overlapping each object and adding extra walls to the modifier each cube now has some extra walls. However, the overlapping modifier creates that artifact on the outside. (Someone smarter and more knowledgeable than I will have to address exactly what is happening there.)
Above: I moved the modifier cube to be just inside each cube. The walls are cleaner now!
Above: Finally I sliced my shell cube in half in my CAD software and loaded it as a modifier for each cube instead of using the generic shape cube. Adding the walls was now very easy, and I didn’t have to fudge around with any kind of alignment. (The right-most object is the modifier object.)
I am not an expert at this! I just hope that this made sense and is helpful. I again recommend the Maker Muse link I provided because he goes into far better detail than I have. If nothing else I think that his video will give you a better jumping off point to know exactly what to search and use!
