Mercedes A-Class W177 Left Rear Bumper Trim (Robust)

Design a 3D CAD model of an automotive rear bumper trim piece for the LEFT side of a Mercedes A-Class W177. Overall dimensions: - Height: 340 mm (vertical) - Width: 190 mm (horizontal) - Depth: 50 mm maximum Shape: - The part is a thin aerodynamic trim panel with a slightly curved surface to match a car bumper. - The front face should be gently convex (bulging outward) by approximately 4–6 mm from center. - The top section should be slightly narrower than the bottom, creating a subtle taper. - All outer edges should be smoothly rounded with fillets of 5–10 mm. Thickness: - Uniform wall thickness of 2.5 mm. Back side (mounting features): - Include 4 evenly spaced snap-fit clips aligned vertically. - Each clip: 10 mm wide, 3 mm thick, with a slight outward angle (5–10 degrees) for flexibility. - Add 2 cylindrical alignment pins: - Diameter: 5 mm - Length: 8 mm Design constraints: - The model must be a single solid body. - Avoid sharp edges; all transitions should be smooth and manufacturable. - The part should be lightweight (target similar to ~90 g plastic part). - Ensure the geometry is suitable for 3D printing without extreme overhangs. Orientation: - Model the LEFT side version (not mirrored). - Outer face should be clean and continuous (visible surface).
