GEPRC KHX (KHX5, KHX6, KHX7) DJI Air Unit and antenna mount

thingiverse

I designed this mount for my GEPRC KHX7 specifically to fit the DJI FPV Air Unit module with stock DJI antennas. This design should work well on other frame sizes, including the KHX5 and KHX6 models. If this works out for you, please share your experience in the comments. The mount is designed to provide just enough pigtail length to reach the antenna connectors with a bit of slack. The Air Unit will press firmly against the back wall, keeping the antenna connectors securely locked in place without needing hot glue or similar adhesives. There's a cutout around the base for securing the air unit with a zip tie and a wire channel along the length of the base to allow the wiring harness to run under the air unit and back to the center of the frame. To print this mount, use supports on its side (this orientation should result in a smoother mating surface where the bracket mounts up to the frame). I printed with 60% overhang supports touching the build plate only. After experiencing a failed print due to the nozzle knocking the print loose, I printed with a raft to ensure success; however, I believe a raft is unnecessary if you have good bed adhesion. I printed this mount in PETG with 20% infill but think you could probably go lower to save weight, and that's entirely up to your preference. Not sure how well this would print in TPU, but I'd appreciate it if someone could try printing it in TPU and sharing the results! To secure the bracket to the frame after printing, you'll need four button head M3x6mm bolts and four M3 nuts that will be pushed into the recessed holes. Use a pair of pliers to force the bolts in if they're having trouble fitting, and they should fit snugly to allow for easy tightening without spinning. This is my very first design, and I'd love it if you could let me know in the comments section if this has been helpful to you. Just knowing that this has made a difference for someone is reward enough! I've included a .step file to encourage modifications; please let me know if there's any other format you need.
