QAV250 dual antenna holder

thingiverse

I designed this adapter specifically for the Spektrum dual-antenna receiver that's part of my QAV250 setup. Initially, I had envisioned mounting it behind the Lumenier Vibration Damping Camera Plate using the second set of standoffs, but multiple options can work (see photos for examples). It's possible to mount it using screws on top of either the 2nd or 3rd set of standoffs with the screws oriented towards the front or rear. If you're not using a camera plate, this would be your best option. Alternatively, you can use silicone isolators from the camera plate for mounting purposes. In such cases, the most suitable approach is to screw these isolators into the standoffs, moving them slightly further out than intended, but silicone isn't an issue here. I plan on utilizing these isolators to attach the camera to my quadcopter using the 1st and 2nd set of standoffs. This setup has its advantages – you can make use of the four extra lock washers located underneath the front isolators, ensuring the camera won't be angled downward. This design caters specifically for 3mm or 1/8" antenna tubes. Intentionally made holes slightly off-center by .1mm provide a snug fit that allows antennas to be removed easily during travel or storage. 05/14/15: Initially, when printing this in PLA material, the 3mm antenna tubes had a perfect fit. However, I discovered a significant difference when trying it out with ABS yesterday – they were way too tight. In response, I adjusted the size of the antenna holes and included an added spacer for the front standoffs to account for any potential mounting scenarios involving camera plates.
