I made this after having a breakage of the antenna fitting from the receiver module inside the goggles.
The construction of these goggles leaves a lot to be desired, removing and refitting antennas to the goggles inevitably caused the SMA fitting to break off the PBC, I was able solder it back but after seeing the fragile nature of the construction I decided to make this support.
Note you will need a short SMA pigtail lead with a right angle chassis mount fitting on the outer end, the one I have came from BangGood and cost a few dollars as well as some double sided foam core tape to stick it on with.
This odd looking contraption has certainly made the goggles more robust however they no longer fit in the original case. (That's a pain) it also means the antenna is mounted a little further away from your head in theory improving performance, in practice the setup performs no worse than original.
I printer this in PLA, colour of your choice (black matches the goggles) I used 60% infill anything around this figure should be fine.
Orientate it upside down on your print bed, no support required.
