Dude would be much easier to make a custom doorbell with a microcontroller with wifi (Pico or ESP32). With ESP32-CAM even have a video feed / screenshots. Toda

Dude would be much easier to make a custom doorbell with a microcontroller with wifi (Pico or ESP32). With ESP32-CAM even have a video feed / screenshots. Today it's never been easier to make custom stuff -- 3dprinting and even PCB manufacturing can be done as a service, no need to buy. Although I would use a dev board microcontroller for $7, so no need for PCB. And doorbell case also doesn't have to be 3d printed, can make it from wood or metal, if you prefer.
