itsFPV ERA 5 O4 Cage Side Antenna, Rear Bumper GPS

First, thanks to chimmeyewegul who created this nice O4 cage.

I slightly widened the inside of the antenna holder so the antenna head sits deeper. Mainly, I wanted a bumper to protect the frame's rear carbon plate, so I removed the rear part of the O4 cage and created a separate part as a rear bumper.

There is a flat "pure bumper" version, and another that fully encloses a BZ-181 GPS and includes an additional 6S balance plug holder on top.
