Sphere Dissection, Trisection, Three-Piece Puzzle

3D model description

Sphere Dissection into Three Congruent Pieces (Trisection)
Support and Raft Needed
3D design allows us to play with mathematical and everyday objects. What if we apply a Reid dissection of a cube onto a sphere? The result turns out to be appealing, too. Nice and smooth, it could be interesting for children to play with.

Of course, it is a bit challenging to print because of the spherical surface. Support and raft are thus needed.

The sphere has a diameter of 50mm. Two versions are included. The inner hollow sphere has a diameter of 25mm. The critical dissecting point is a centroid in this case.

Have fun!
