This is an improved version from klinsman21 from ThingiVerse.
Since Makerbot let ThingiVerse die and I'm not able to log in again. I put these files here.
What I've done was to add some holes for the cable passthrough and some “pins” so the mount will fit to the case.
I did all changes via PrusaSlicer.
