See https://www.printables.com/model/507270-harvestright-camera-mount for @dgardner_169337 excellent solution.
I need a new bracket to fit the camera that I had. It needs 4 x M3 x 12mm bolts.
Printed in PLA+ with 15% infill, can use other materials.
The author remixed this model.
Changed the bracket to an L shape with holes that are compatible with Ubiquiti's G4 Instant
