IDSA pin

This IDSA pin is a miniature herringbone-toothed planetary gear bearing. Because the pin is printed in one piece, there is no way to assemble or separate each of the constituent gears. Amazingly, this design is only manufacturable via 3D-printing, which makes it perfect for the maker-oriented IDSA conference. The pin fastener is attached to the back of the "sun" gear, which would keep the IDSA logo centered and upright as the core ideas of the IDSA 2014 conference - design it, build it, fund it - revolve around the IDSA logo.
