I am not carrying a GoPro on my cinelog35-v2, Walksnail or DJI fpv cameras are good enough quality for me, thus I wanted to use the space for a protection bumper / canopy that might help the battery too in case of a crash. Havent crashed it yet so need somebody to test :-P
No support needed, print in same orientation as placed on drone. Grid infill 10% seems resonable.
PETG/PLA/TPU any should work, with prons and cons.
