Comment on Merging two objects (I'm a beginner)

Do you have some pictures and drawing to explain what you want to achieve?

I agree with the comment about using something simpler than Blender. Blender is the right tool for organic shapes and for sculpting.

What I understand is that you have two models, one for a phone case, one of a “hole” for fixing a magnetic holder.

I use OpenSCAD. With this tool, this would be my logic (could be replicated in other tools :

import the mag holder stl
create a rough shape, like a cylinder, that would fill the hole
make a “difference()” between the cylinder and the mag holder. This way, the cylinder has the shape of the complex hole. You can then use this shape to make a hole in the stl of the case
import the case
import the mag holder once again / or add a volume the shape you want
use “difference()” between the case+mag holder and the complex hole shape to clear the hole

you can enhance this process by creating a negative shape of the buttons holes

Image is my crude sketch on what I wanna do. Image 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.
  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.

Thanks! This sounds a lot, but I wanna try making it. I like modifying things to suit my use, and this sounds like a fun learning endeavor. I’ll perhaps look at OpenSCAD. This sounds similar to some of the information I found on blender (making shapes to delete areas). I need to play with these tools to get more facile at doing this.

I don’t have a picture readily availble at the moment, but the stls are www.thingiverse.com/thing:4935721 for the phone case (I just wanna use the right side) and www.thingiverse.com/thing:5704716 for the holder. It’s a little more complex than just a magsafe holder, it has a quadlock mount integrated.
