This basic object can be used to mount a Raspberry Pi camera using 2mm nylon bolts inside an IP67 junction box. It is 57.5mm wide and fits inside certain IP67 Sealed ABS Plastic Junction Box measuring 73x80x53mm.
I created it to mount a camera inside a weather-proof box to serve as a security camera. The cylinder can be rotated in the box to adjust the camera pitch angle.
Centre hole : 4mm diameter to accept 3mm threaded bar
Total length : 57.5mm
Cylinder radius : 10mm
Centre section thickness : 10mm
Recommended nylon bolt length : 15mm
The cylinder doesn’t have to cope with many forces so an infill of 10-20% is fine. As with all printed holes they are best cleared with a suitable drill bit especially the holes for the 2mm camera bolts.
I used 3mm nyloc nuts on the end of the threaded bar to secure the cylinder in position.
The junction box used is an Evatron IP67 ABS (DE Series) 80x73x53mm with 2 x M20 Knockouts. I like this style because it comes in a version with a clear lid.
