Triple Shift Too

This CAD model was designed by Oskar van Deventer, copyright (c), 6 October 2024.

Triple Shift Too is a variation to a classic puzzle with three idential pieces. Triple Shift Too requires 90 moves to solve, as each of the pieces has the smooth inner surfaces replaced by 30 staircase steps. An earlier wooden version of this puzzle had 5 staircase steps. 3D printing enables to increase the number of step dramatically. However, one cannot increase too much, because then the surfaces become smooth again, and the number of steps becomes one big coordinated motion.
