Description

This arm is designed to mount Raspberry Pi Zero W 2 with the camera to the Ender 3 V2.
The compact size of the Pi board allows one to embed it into one of the mount's joints. The arm has 4DOF which is more than enough to find the best camera angle.

Assembly tips

The arm joints are assembled with M3x8 screws and threaded inserts.

Raspberry Pi power source is DC / DC converter, which is mounted on a top panel inside the printed case. The converter is powered from the printer's 24V power supply, so the board is on when the printer is powered. There is also plenty of free space inside the printer to mount a DC/DC converter inside if you prefer this option.

Consider using micro USB OTG cable to tidy board to printer connection and don't forget to secure all the wiring with zip ties.
