porsche-inspired sports car 3d model

Ultra-smooth minimalist sports car body inspired by a Porsche 911 silhouette. Create a watertight, manifold 3D model suitable for STL export and 3D printing. The body should be extremely clean and simplified, with almost no surface details. No door lines, no mirrors, no badges, no windshield wipers, no handles, no vents, no grilles, no trim pieces, and no visible panel gaps.
