Tower of Hanoi stackable blocks by edmo Mar 2, 2013

## Description

This is a set of stackable blocks. The largest one measures 2" in diameter at the base.

I set layer height at .2mm, 3 perimeters, 3 solid layers and infill at 40%.

I created these as part of a project where a robotic arm could be taught to solve the Tower of Hanoi problem (look it up and try to solve it BEFORE you cheat and look at the answer). They're a neat desk toy, too. Enjoy!

## Instructions

These instructions come edited from Wikipedia.

The puzzle starts with the [blocks] in a neat stack in ascending order of size, the smallest at the top, thus making a conical shape. The objective of the puzzle is to move the entire stack to another [position], obeying the following rules:

1. Only one block may be moved at a time.
2. Each move consists of taking the upper block from one of the positions and moving it to another postition on top of the other blocks that may already be present in that position.
3. No block may be placed on top of a smaller block.

With three blocks, the puzzle can be solved in seven moves.
