traditional kokoshnik 3d model

Create a wearable 3D model of a traditional Russian kokoshnik for a human head, inspired by the reference image. The kokoshnik has a tall, symmetrical arched shape with a pointed top and smooth flowing silhouette. Real-world wearable scale: width 180–200 mm, height 120–140 mm, base thickness 2.5–3 mm. The inner bottom edge is curved to follow the human head shape and fits comfortably on the forehead. The surface contains raised ornamental relief: floral and swirling filigree patterns inspired by traditional embroidery, with soft rounded edges. Ornament relief height 1.2–1.5 mm above the base. Lightweight structure suitable for long wear. No sharp edges. Geometry only, no textures. Color: neutral white or light gray. Output format: STL or OBJ. Clean, manifold, watertight mesh, ready for 3D printing.
