About this 3D model

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!
