Waveshare 7.5inch wall mount

BOM

1. 4x M2 threaded inserts
2. 4x M2 screws
3. 2x Mount points (I used wall plugs)
4. 1x Waveshare 7.5inch E-Paper Hat Display Module

Modify model if necessary

The mounting holes are 117mm apart. If you want to change that, edit the Fusion 360 file and export the “back” component before printing it. There's a parameter to help you do that.

Print

I printed the parts using PETG but any other filament should be fine.

The “back” part needs a bit of support just under the mounting holes. The 3mf and gcode files already contain these supports.

The other parts don't need support.

Code

The codebase I'm using (tailored to my specific needs): https://github.com/Crocmagnon/display-epaper. I'm using https://gokrazy.org.

Assemble

1. Add M2 threaded inserts to the frame
2. Put the display in the frame, face down, flat cable near the notch
3. Add the wedge on top of the display, to press it towards the frame
4. Mount the back, mounting holes opposite to the flat cable.
5. Assemble using M2 screws

I drilled a hole in my wall to let the flat cable access the raspberry pi, mounted in a closet just behind. The hole is hidden by the display.
