3D Model: The Object Is A Shark Fin Bone Structure, Resembling A Tall, Narrow Triangular Fin With A Curved Base. The Structure Consists Of Long, Parallel, Vertical Rays (thin Rod-like Struts) That Extend Upward From The Base Toward The Tip Of The Fin. These Rays Are Straight, Evenly Spaced, And Slightly Flexible-looking, Tapering In Length From The Leading Edge (front) To The Trailing Edge (back). At The Base, The Rays Are Connected By A Series Of Angled, Crosswise Segments Forming A Stepped, Lattice-like Joint. This Joint Creates A Fan-like Curvature That Allows Stiffness At The Root While Maintaining Flexibility Toward The Tip. The Overall Profile Is Triangular, Widest At The Bottom And Tapering Smoothly To A Thin Point At The Top. The Rays Are Semi-transparent And Organic-looking, With A Subtle Ribbed Texture. It Is No Wider Than 4 Mm At Its Thick Point. It Is Relatively Falt
