About this 3D model

How do you share a spherical object such as a water melon or orange among four people? Here is a dissection of a sphere in the Yin-Yang style. It is an interesting way to slice a sphere for aesthetic purposes. This is intended to be an introductory project for students to learn about the art and math of 3D design. The focus is to navigate in the 3D space. You need two copies of A and two copies of B to make a sphere. A and B are mirror images of each other. The sphere has a radius of 50mm by default. They can be printed at 5% infil; then, about half way through the printing process you can put a small magnet in the head of each for easy assembly. Have fun!
