Beta95X V2 Bottom Plate

# Beta95X V2 Bottom Plate

Since BetaFPV recycles their V1 camera mount as a bottom plate for the V2, I decided to build a better bottom plate. I didn't like that the quadrotor can't be placed horizontally at level and that the USB port is just not accessible, no matter how you flip the flight controller.

So this design fixes
* __leveled placement__ and
* __USB accessibility__

and (optionally) adds
* __landing gear__ and
* and a cable/receiver __compartment__.

## Notes

* All models require support except for the _easy print_ versions, that dispense with the wings/flaps that close the lower notches in the molded frame. The version with USB also dispenses with the protrusion for the USB connector.
* Other file names are long but pretty much self-explanatory.
* Print using 100% infill.
* The landing gear design is inspired by the Umma95.
* The 1 mm spacing around the USB port is intentional to avoid the transmission of vibrations from the frame to the flight controll
