NYLON Windmill Flange to reduce Bird Mortality

This is the mounting flange for a 2.5 meter 8 blade electrical generation windmill.
The flange is printed in NYLON so as to provide a shore 45 single piece flexible connection to the main drive shaft from eight fiberglass blades. The parts were printed on a 2BEIGH3 3D Printer. Details of the printer can be seen at:
