Stereographic projection sphere

This 3D-printed sphere demonstrates a stereographic projection, a way to map the surface of a sphere onto a flat surface. Imagine taking a picture of the sphere from the top and stretching it out onto a plane. This model helps you see how every point on the sphere corresponds to a point on the flat surface. It’s a great way to explore how 3D shapes can be represented in 2D, making it easier to understand patterns, symmetry, and geometric concepts. Perfect for anyone curious about math, geometry, and projections!
