Hi,
did this for a collegue, maybe someone can use it.
Sorry for the german filenames had no time to clean it up.
the freecad files are included so you could mess around with it and improve it.
I personally never used it - just printed the files.
There are 2 clamms build of 2 Parts each that are mounted “in” the wall ->_13.jpg
There are “slides” to slide in the Display with the mounted raspberrypi
The red printed parts are the springs that clamp the part in the slides, it snaps.
To release it you have to push the red latches from top and bottom to the middle.
Materials:
You may need some screws and some inserts
You may need additional screws to mount the case to the wall
Attention - the Waveshare-Wallmount-V1-20-Display-MountKorb file seems to have some minor bugs - repair or ignor them - my collegue said it is still usable
