Flexible Landing Gear for Quadcopter "Crossfire" Version 3

Further improved version of my flexible landing gear for MikeyB's quadcopter "Crossfire" or my derivate "Crossfire Mini".

(Compatibility with Crossfire 2 is about to be tested)

After hard landings, even the version 2 of my flexible landing gears broke. I detected and fixed the critical regions, now it's really stable.

In comparison to version 1 and 2, it is now printed upside down. The part pointing towards the quadcopter's arms has been redesigned and is now very stable.

The flexibility in the "bended double leg" proved successful, so I kept this design. However, the ball at the end had to move because of the "upside down" redesign.

The holders for M3.5-M4 nuts are still there. Please adapt their size to fit your nuts! Their distance from the bottom plate has increased such that your screws should stand out at least 12mm (1/2in) from the bottom plate.
