I could not find a decent 45 degree mount for the Wyze Doorbell Pro model. The one I did find had a 5mm gap between the mount and the doorbell.  So I created my own. This version has near-zero gap between the doorbell backplate and the wall mount.  It is also fully reversible so it can point 45° left, or 45° right.    

I created this in Ondsel ES (Freecad).  

Printed Settings:

Material: Generic PLA 

Layer: .24 
Walls: 8 loops.
Infill: 10% gyroid
Top/Bottom: 8 layers

Arachne engine. 

I just installed this 2024-4-6 so I cannot yet verify that it will hold up throught a minnesota year. But my other PLA prints have survived well enough.
