yin-yang sphere 3d model

A perfectly balanced Yin-Yang sphere sculpture designed for 3D printing and magnetic levitation display, sized about 100 millimeters in diameter. The sphere is divided into two swirling halves — one glossy black and one pearl white — with the classic small opposite-color circular dots inset on each side. The surface must be smooth and continuous, without texture or seams, suitable for printing in two interlocking parts. The Yin-Yang line should curve fluidly around the sphere, forming an organic “S” boundary. Each half should have a precise inner cavity to optionally insert a small balancing weight or magnet core. Beneath the sphere is a minimalist round display base (120 mm diameter, 35 mm height) designed to house a magnetic levitation module. The base should have a slightly recessed center cup to help stabilize the magnetic field and a thin circular LED light ring around its outer edge that emits a soft warm-white glow upward. The base finish is matte black anodized metal style with a subtle reflection.
