This is a Raspberry Pi camera post mount for my hanging v plotter/polargraph.
It is intended to make time lapse videos of the machine in action.
First test of time lapse with this setup: https://youtu.be/_Gf2_47hRvc
Colours are off because the lighting is bad.
It uses a long flex cable that is fed down a 10mm OD Aluminium tube and a cheap wide angle lens that screws into the case. (Look for mobile phone clip on wide angle lens on ebay)
At present the case is just glued together with a few drops of superglue (it has no fixings as I couldn't include printable fixings without making the case much bigger). The camera PCB is held in place with a small foam spacer (I used foam tape).
The machine is running vPiP and my dual stepper Pi 2/3 HAT.
