DJI O4 Air Unit Antenna Protector Caps

Hey everyone,

here's a super simple yet effective design for you: protective caps for the DJI O4 Air Unit antennas.

I fly a GEPRC Cinelog 30 myself and was tired of the unsightly scratches on the antennas after a few "rough" landings. These caps perfectly protect the delicate ends.

I print them from PETG, and they hold rock solid for me just by clamping. I didn't even have to glue them, and I've never lost one in flight. Just push them on, and you're done!

Printing is super easy and, of course, requires no support structures.

If this small design makes your life easier, I would be incredibly grateful for your support!

Please like, boost, and download the model. Every rating and download helps me immensely to earn points in the MakerWorld system. I reinvest these points directly into new filament for more cool projects for the community.

Thanks for your support!
