Summary

This is designed to be printed with a flexible TPU material, the tolerances are very tight, so PLA would not work.

The mount is designed to be tight to hold a camera on an FPV drone, but you can adjust/scale the model in all directions by 0.5mm to change that.

I have printed this in 95A TPU.
0.2mm layers, 4 walls, 70% infill
Print the model on the side lens cutout facing up
Should be printed with supports for the actual mounting point.

I have also added a 4mm inner and outher brim to prevent the model from unsticking, but you could skip that if printing on a sticky bed.
