The handle of a micro wave oven broke.
I can't just order a replacement part because I can't even attach the new one.
The problem is that the screw heads are somewhere on the interior side of the door, which cannot be disassembled (non destructively at least). I wouldn't even do it because of safety reasons.
I have access to the threads of two loose and captive screws to work with (indicated by the two red lines on picture one). The screws are not machine screws, but screws for plastic like in the attached picture.
The plan is to 3d print the plastic part of the handle and reuse the front aluminum cover.
I don't want the handle to be loose, so I'm looking for suggestions to attach the new handle. I have a lot of ideas, maybe I will share them later if they are not mentioned at some point. The main problem is: how to attach something when all I have to work with is a loose, non machine screw ?
