The Stone-Joint Square Cover, (Bicylindrical) Steinmetz Solid

The main and left views of the Stone-Joint Square Cover are both circles, but the top view is a square.

This work is a geometric solid formed by the intersection of two perpendicular cylinders.

This series of works will be expanded to include intersections of three cylinders, four cylinders, six cylinders, and ten cylinders.
This work uses Print-in-Place, separate concave-convex combination printing, half-separate printing, and free choice.

Stone-Joint Square Cover, Steinmetz Solid

In geometry, a Steinmetz solid is a solid formed by the intersection of two or more cylinders of equal radius.

The Stone-Joint Square Cover is a method for calculating the volume of a sphere first discovered and used by the ancient Chinese mathematician Liu Hui, similar to the infinitesimal method. Because the model it uses resembles a stone-jointed square box, it is called the Stone-Joint Square Cover.
When a cube is intersected by cylinders from the vertical and horizontal sides, the common part of the two cylinders.
