This is a angled mounting bracket for a Wifi door bell, since most door bells are mounted on the door frame, the camera is not centered and sometimes you won't see who is in front of your door.
I designed this simple angled mounting bracket, I needed a 20 degree one but since I am going to upload here, decided to make a 10 degree and 30 degree versions too. It is designed to put it under your door bell without disconnecting the wires.
The mounting surface is around 122mm x 55mm (This is the back side size of my door bell) The actual bottom is smaller because of the angle.
Printed with PETG and screw holes are not till the bottom, all holes are 0.4mm higher but you can screw through this easily, I designed like this, so the PETG won't lift up with small printed sections at first layer.
The Wifi video door bell I have is a Elec IDC-25, but same door bell is sold with different brand names like Alecto, Doorsafe and some more.
