Meteor75 Pro ELRS 2.4GHz Mount

I designed this lightweight 2.4GHz T-antenna mount after being a bit disappointed in my AIO's built-in receiver performance. Designed to upgrade your Meteor75 Pro frame to an external RP1 receiver at the cost of a couple grams. This mount shifts and locks the antenna to the rear of the frame to maximize reception, keeping the active elements positioned safely above the prop ducts to prevent strikes or snags. No clearance issues with standard 1S batteries using this design. Zip ties can be used to secure the antenna to the mount, but I've found they're not really necessary. 

Made to use the Meteor75 Pro's frame to secure the mount in place. I don't have other whoop frames on hand to test fit, but I assume this will not work with any other frames. Although the mount is designed to be a friction fit, a single M1.4 screw can be used behind the main 25.5X25.5mm mounting points to lock the mount to the frame.

This model features tight 0.15mm tolerances to achieve a satisfying, secure snap-fit over the injection-molded frame. MSLA/SLA printing with a durable, non-brittle material is strongly recommended. I used HeyGears PVC-like PAF10 resin and have had good results. Orientation is pretty forgiving, but I would recommend not printing it with the curved side facing the build plate since supports will wrap around the structure and make it difficult to remove. I've had good results rotating the model 45 degrees with the interlocking tabs facing the build plate.

If you do print this with an FDM printer, I strongly suggest not using brittle filament to avoid having the thinner tabs snap off the first time you attach the mount, TPU and smaller nozzles will be your best bet.   

STEP file with the mount, mock antenna, and mock frame is included for easier tuning to fit your needs.
