Laser Cut Quadcopter Frame

This is a quadcopter frame that I made using a laser cutter. It is designed to be cut out of 3.1mm (sold as 1/8") baltic birch plywood.

The whole thing is glued together. I don't have time or space to describe the whole build process here, but I have an instructable that give complete instructions for building a quad using this frame:
