I am using Pi Zero W and Pi Camera module for my Octoprint needs. I don't have a long camera cable so I need to attach the Pi somewhere as the platform moves. So I join the camera arm to a pi case :)

Original arm is from https://www.thingiverse.com/thing:2267182 Original case (For Pi Zero) is from https://www.thingiverse.com/thing:1848639 If you use Pi Zero W, use this for top part of the case: https://www.thingiverse.com/thing:2165844

I use the camera mount from https://www.thingiverse.com/thing:2307335 If you use pi camera module v2.1, use this for the back part: https://www.thingiverse.com/thing:2307685

The short camera cable is from the official pi zero case: https://thepihut.com/products/official-raspberry-pi-zero-case
