I designed this antenna holder for my naked GoPro BetaFPV Beta95 CineWhoop. Simple, flexible, easy to print. I attached the modifiable f3d archive, so it is easy to edit with Fusion 360.
Check out my unbelievably awesome naked GoPro mount which fits GoPro 5/6/7 models universally, and is (more-or-less) crashproof!
