futuristic cube 3d model

Create a precise 3D model of a rigid hard-surface armor panel inspired by the uploaded image. The part is a molded plastic toy component with the following features: – A broad central curved plate forming a smooth convex surface. – Symmetrical stepped side fins on both the left and right edges, composed of multiple angular segments extending outward. – Four rectangular mechanical tabs on the top and bottom edges, evenly spaced and protruding outward. – A recessed concave arc in the middle of the panel, creating a distinctive shape transition. – Crisp mechanical lines, sharp bevels, and straight hard-surface contours throughout the entire piece. – Uniform plastic thickness, no organic curves, and no deformation beyond the intentional curvature of the central plate. – Maintain the silhouette and proportion exactly as shown, ensuring the piece is symmetrical and rigid. Produce a clean, watertight mesh suitable for 3D printing, with no invented or abstract geometry.
