Hysteresis Key is a maze puzzle, where the object is to pull the key out. However, one can only move the key in and out. The movement of the key moves a red pin sideways. The puzzle is solved by pushing and pulling the key just by the right distances. Too far and the puzzle resets itself. This version is an experiment with transparent PLA printing. Thank to the single layer of transparent PLA, one can see the position of the red pin in the maze, which makes the puzzle accessible.
