Akaso Brave 4 Quad Copter Mount 20°

thingiverse

I expoxyed a Velcro strap to cap so it holds the whole package together. Then to mount to the quad, I used 3M extreme mounting tap and some foam as well as two zip ties to make sure it doesn't fall off in crashes. The tolerances are very tight so you might want to expand the model very slightly in your slicer but printing on a Prusa MK2S yielded a good fit with no rattle.
