Hi Shapeways Puzzles fans,
Illegal Gear Triangle features three gears meshing in a triangle. As most people know, gears are not supposed to be put in a triangle, as they would then lock up. The issue was discussed by
Numberphile, showing some
Henry Segerman three-gear example that do turn together, albeit not in a plane. The gears feature in the Illegal Gear Triangle are
herringbone gears with threefold rotation symmetry. All three gears turn in the same clockwise direction, gear A driving gear B, B driving C, and C driving again A.
