Eufy doorbell e340 configurable backplate

I hope this helps anyone looking for something similar.

This is not an angled mount, but you can easily add an angled version if needed. It is a backplate designed to cover the junction box behind the doorbell. It hides the mounting screws and includes countersunk screw holes.

The design uses M3 hardware. No heat-set inserts are required, that is, I used one, but not melted in; Mounting holes hold the heat-insert and just holds it in place with a 0.5mm thick wall... If you need M4 hardware, you can adjust the relevant parameters in the included FreeCAD file and export your own version.

The height, width, hole sizes, bevels, device-hole position, and screw-hole positions are all adjustable in the parameters

I’m mounting this on a rough stucco or pebble-dash exterior wall, so I configured the model with extra-long standoffs around the mounting holes. But you can adjust plate thickness, standoffs and actually any parameter that makes this happen.

Designed by human, afer few iterations my GPT 5.6-sol assistant took this to the next level with me and end results are exactly what I had pictured. Hope you can use it too!

The STL is just my own setup - be sure to measure your junction box and how you want it too look , adjust parameters (and  press F5) and then export your custom model!
