I like the simplicity of Carsten's ESP32 Cam Clamp and how it holds the camera in place. However, I wanted it to fully cover the front and use it with a 120 degree wide-angle lens, which doesn't fit through the hole in the original design. So I extended it to the full height of the PCB, and added a slot for the camera so it can slide on to the PCB. I also made a version with a connector for Jack's excellent articulated arm (12mm version).

The 18650 battery shield was bought here and the case design is by Dust.
