Top plate mount for GoPro Session 4/5 cage with back mounting.

4 versions:

a - first version, directly replacing two top side plates (not recommended)

b - second iteration of the a version (also not recommended)

c - third version intended to be sandwiched between the original carbon plates

d - final version (so far), similar to version c with just the back part cut out to reveal part of the holes in the top plate (I mounted a pagoda there)

I am also running zip ties through the side holes near the back posts.

Tested with Avan props, other props might result in jitter.
