~500 mm Honeycomb Quadcopter frame

A larger variant of Dennis Baldwin's mini quadcopter honeycomb frame, which can be found at http://www.thingiverse.com/thing:463579
I had this printed in ABS at 30% infill. Some minor filing was needed to make the parts fit together, but it's very light and flies really well.
In the future, I may upload a version 2.0 where the parts fit together a bit better.
