3D model description

Sphere Trisection/Dissection: Three Congruent Pieces

Yet another appealing dissection of a sphere into three congruent pieces. This design is based on a Reid dissection of a cube ( It is interesting to embed a sphere in a cube and play with all sorts of manipulations! Of course, it takes three copies to make a sphere. I have included a shelled one, too, just to add more flavor.

####About Printing

There is a small hanging piece in the part. It prints okay on my printer. If necessary, please add some support. Alternatively, it can be rotated and then printed with support for the spherical bottom.
