Tower of Hanoi stackable blocks

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!
