This it's a camera enclosure/lens adapter for the rasperry pi.
The holder links are a "steal" from: https://www.thingiverse.com/thing:2875976
I printing this on PLA, 3 perimeters and 20% infill with a 0.4 nozzle at 0.2 layer. Only the raspberryCamA and raspberryCamA_h pieces requires support.
4x M2x8 screws (with 2 it's ok too)
Note: the lens adapter didn't have any thread, the thread pitch make this too small to print (I think), so I'm counting on the thread of the lens to be hold on the plastic, so this probably won't work on plastic body lens only on metal ones.
