Middle finger turtle mode fin

Middle finger shaped fin for EMODIA frame with TwistLock. Used to keep atleast 2/4 propellers off the ground when the quad is upside down. This helps when flipping the quad back using turtle mode/crash flip. Angle is 45 degrees so that when you're flying, the finger points somewhat up. Print with >2 perimeters and at least 15% infill to ensure adequate strenght.
