Merging two objects (I'm a beginner) (lemmy.world)

Hello, thanks in advance for any help. I have a little project I am trying to do-- I would like to merge a "Mag quadsafe universal adapter" with a Galaxy Fold 3 case. I have both STLs and i began playing with blender yesterday, and it's possibly a little above my head.

What it seems like the steps are from my (peprhaps simplistic) point of view:

  • trim the openings on mag quad adapter to fit the camera lens and side buttons when it is perfectly centered on the case.
  • delete a square the exact size of the magsafe quadlock adapter that is perfectly centered on the back of the phone case
  • put the current model from the mag quad stl in thus square

The only thing I've been able to accomplish thus far is centering the mag quad adapter on top of the case. I cannot, for the life of me, figure out how to trim in to fit the camera and side button openings....

Any help is greatly appreciated, even if it's just a starting point.

Edit: This is as far as I got in Tinkercad/Blender/Automesh -- I had trouble actually modifying the shapes in any way in all programs (I am an absolute beginner at this, but I wanna learn and have access to a few different makerbot printers):

This is my crude sketch on what I wanna do.

This is the magquad holder I want to integrate directly into the case.

I don't wanna stick the holder on my naked phone, and if I put the holder on the case as it is, it will likely be too thick to charge.

OK that's clear.

What I would do :
I would remove the corners of the mag holder.
For this, I would make a big cylinder to catch what I want, and use an "intersection" to get only the center.
https://piped.video/watch?app=desktop&v=Z3sgFGeoQTs . Try it first with a cylinder, but actually, I would use a cone or a really big sphere to have a chamfer.

Then I would place my new shape like you on the case. Without the corners, you would not get the troubles of removing the complex shapes for the camera and the buttons.

I love this. This would make it easier. I can use the exact same cone to "cut" the case. I'll also be able to perfectly center the cone on the mag quad adapter (not sure if the stl has is 100% centered or not, but this way I can get it perfect.

I'll play with this. Probably won't have time for a few days, my days are busy. I tried using sphere deletion in blender yesterday, and it was a bit tough since it was my first time using any 3d design software.

I think this is probably the best suggestion for how to accomplish this, and I'll be able to focus on doing it soon.
