Tower of Hanoi

thingiverse

The Tower of Hanoi is a mathematical puzzle consisting of three rods and a number of disks of different sizes that can be stacked on top of each other. The objective is to move the entire stack from one rod to another, obeying certain rules. There are only two ways to do this: either by moving the largest disk first or by moving all smaller disks to one side before moving the largest one. In both cases, the smallest disk must be moved last, always on top of a larger one.
