The file 'Self-aligning Hex Socket + Vase 3D Printer Model' is (stl,f3d) file type, size is 943.8KB.
This "socket" uses a hexagon helically rotated 1/12 of a turn (in both directions) to nudge nuts into the correct alignment before entering a hex-shaped hole.
This idea is useless given the existence of 12-point sockets and the Gator Grip, but the geometry is fun to look at. I also stretched it into a model for spiral vase mode.
