A pocket transmission printed in one piece, nine bodies, zero assembly: a 12-tooth sun rod spun from the top knob, three planets on a slotted carrier, and a thin ring gear that climbs a hidden 3-wave cam as it revolves. Slide the collar through the side windows to shift a real dog clutch - Drive (1:1), Neutral (freewheel) or Reverse (exactly one-third speed, backwards) - while a seven-segment digit ring counts every lap through the viewing wedge. Shift to Reverse and the odometer physically rolls back.
