Battery protection cradle for ImmersionRC Vortex 285

The Vortex 285 is a nice quadcopter, but a simple shock may let the propellers severe the battery. You can see what happens then on the last photo, and the landing was quiet soft.

This cradle is to protect the battery from the propellers, when arm retract while landing / crashing. It clips on the model using existing plates and screws. Total weight: 9g.

Redesigned on Fusion 360 (first one had mistakes).
