Hi. I made my first hexcopter using PVC. It worked great, but it was, of course, quite heavy. Since then, I've come up with a new frame design and motor mount based upon extruded 12 mm carbon fiber tubing. I was able to test print one of my 3D printed motor mounts and it is incredibly strong, but I don't have a printer to print the final parts. I got a quote from Shapeways and it ran about $270 which is way too high.
This motor mount is designed for the Avroto 2814 motor. Is there anyone out there with a printer that would be willing to trade the design files for the printed parts? The pictures below are of the motor mounts. I also designed a center hub and braces to position the carbon fiber.
