car door panel 3d model

Generate a clean engineering mesh of an automotive front door inner panel prototype. The object is a thin sheet metal part with a rectangular main panel, uniform thickness, two circular through holes aligned horizontally, a raised outer flange, a lower horizontal reinforcement rib, rounded corners, no texture, no labels, no bolts, no cylinders, no extra components. The shape should be simple, symmetric, CAD-like, and suitable as a rough mesh reference.
