The oloid is a fascinating geometric solid discovered by Paul Schatz in 1929.
Its unique property is that it **rolls while touching every point on its surface**, even though it is not a sphere.
This 3D model is designed for easy printing and works great as an educational object, desk toy, or stress‑relief item.
