AtomRC Dolphin nose for DJI O3 with pan servo option

Kind of late to the AtomRC Dolphin party but I am building my first one and wanted a nose for DJI O3 that gave it good ventilation. I also wanted a pan servo but wasn't sure it would work well with CG so I designed two versions. Still not sure which one I will settle on but for now going without the pan servo.

Added a 3rd version (by request) with no servo but allows the camera to be set back facing forward protecting it from direct frontal impact.
Added another 2 versions (with and without Pan) for dual antenna setup.

I borrowed the backing plate from this design https://www.thingiverse.com/thing:5365305. I think 2 screws is enough so I eliminated the bottom screw hole. Embed some M3 inserts in the backing plate to allow you to screw in the nose. A hot soldering iron helps to punch holes in the foam so the backing plate fits after removing the magnets.

Use some VHB double sided tape to secure the air unit.

I printed in black ASA with very low infil (4%) to get it very light but still strong. Organic supports worked well.
