This production-ready 3D CAD bangle model is engineered specifically for modern precision casting, CNC machining, or high-detail resin 3D printing. Built as a wide cylindrical band, it features a high-relief micro-pyramid knurled center channel framed by two raised protective borders.

Micro-Pyramid Knurled Grid: The central recessed track is covered in a high-density, repeating grid of four-sided micro-pyramids, creating sharp geometric relief and dynamic light reflection across the metal surface.

Dual Protective Flanges: Bounded on both sides by smooth, elevated outer rims that protect the textured center from daily surface wear while providing clean structural borders.

Inner Rail Geometry: Designed with a smooth, flat interior profile and softened edge fillets to ensure comfortable wear and effortless post-cast polishing.

Solid One-Piece Construction: Seamless 360-degree cylindrical geometry with zero seam lines, ensuring balanced weight and uniform metal flow during casting.
