250mm Quadcopter Spring Frame

This is the culmination of the quadcopters I have printed so far. It is almost as light as a carbon fibre frame and it bounces off tar from a decent height without taking damage. As you can see from the photo of mine it has survived several head on collisions with trees.
It has mounting holes matched to cobra 2204 motors.

Unfortunately I lost the 3D model of the top plate pictured in my image so i have included a .dwg file with the mounting pattern and outline of the top shell which you can use to model your own top plate to accommodate your battery, camera and electronics most efficiently.
I have included an old version of the top plate which was intended to have the camera on a single axis gimbal.
