Wind Vane

This wind vane is meant to work with a slip ring. It was initially meant as an electrical wind vane to hold a pitot tube and a compass for a low cost wind speed and direction sensor holder. The screw holes are meant for #10 screws. The dimensions are about 8 inches long and 5 inches tall and 4 inches wide at its wide point. This is my first creation for 3D printing so be kind.
