Pitch mount for Logitech C920 camera

A functional pitch controlled mount for the Logitech C920 camera (autofocus, HD) to go in the head of my Droidbot 07 project (https://droidbot07.blogspot.com/2019/01/logitech-c920-camera-pitch-mount.html)

Actuated by a 9g servo allowing ±45° vertical swing.
It utilises a remix of: Logitech C920 Adapter for RaffoSan's Camera Arm by Felwat
