A simple but effective stand for one of the M5Stack ESP32 fisheye camera modules, which attaches via the included wall mount clip & a pair of countersunk head M3 bolts.

The upright is an offcut of regular 20x20mm aluminium box section with a 3mm hole drilled through. Depending on your printer's tolerances you may have to play with the scale to get a good fit (printing at 100.5% will add 0.1mm).
