This is a combination of a few designs I found. It fits the mounting pattern of the XHover Win5 top plate and provides a GoPro mount with slot for a glass ND filter inside with a TBS Immortal T antenna holder on the side. There is a GPS bracket on the back and a slot under the GPS to fit the Crossfire RX.
V2 uses the ball and socket immortal T antenna holder from AirBlade:
V3 uses a taller immortal T bracket and a slightly different GPS bracket with space under it to stash your Crossfire RX
The antenna & LED bar file fits the rear standoffs and provides a place for an LED strip and a hole to mount a coax antenna.

Print upright with supports everywhere at 85 degree overhang angle for the original file that does not have GPS.
I usually print on its side with the antenna holder up using supports. Sometimes a brim can help with the print to keep the small edges upright in the beginning.
