The articulated arm was really good but now I'm using an enclosure have found mounting the camera on the wall is good.
Re-used the Raspberry Pi camera mount from the original Articulated Arm model by Sneaks.
Printed a wall rack and new ball joint connector that can be moved up and down the rack.
Printed the ball joint with a brim.
Attached to the wall with two M5 nuts and bolts.
The author remixed this model.
