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.

    F you’re a beginner then I think my first advice to you is to not use Blender. Start with something like TinkerCad, much easier to work with, and more than adequate for what stated.

    TinkerCad lets you add shapes together, and the neat thing is that there are also hole shapes, negative volumes that you can use to cut away material.

      I’m also a newbie that uses blender, which open source CAD tool would you recommend (if you have any experience with it)?

      I tried with tinkercad, and I struggled. I was again able to align the shapes directly on top of one another, but when it came to modifying the actual shape I could not figure it out- is there a tutorial on adding shapes together or anything, or even carving stuff out?

      I looked and couldn’t find anything this specific. It seemed like a much easier tool to use, but I couldn’t figure out how to do what I wanted. I also used

    So, out of the box, blender is not a cad tool and it’s not a good option for anything that requires any amount of precision- there are extensions that will help, I’d just as soon suggests any other cad tool.

    That said, if you can, link the files you’re using and the, we could give give you a more precise work flow.

    Prusaslicer has some pretty good stl manipulation tools built-in these days. You can merge, split, add common shapes, subtract shapes, etc.

    From the outside looking in, it seems like you should be able to do everything you want right in the slicer.

    I’ve found this to be preferable for working with existing stl’s (not as useful for editing) if you dont have the actual step files or 3mf files available.

    I found windows 3d builder to be very beginner friendly for modifying basic shapes.

    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

    If you want to use blender for this you should be able to use a boolean operation to combine the two bodies you import. Your computer should do the second step for you in any reasonable modeling software.
