The prompt
Create a clean, symmetrical, CNC-machinable miniature sports car body inspired by the classic Porsche 911 silhouette. IMPORTANT: This is a CAD manufacturing model, NOT a render, concept art, toy design, or decorative mesh. OVERALL DIMENSIONS: * Length: exactly 55 mm * Width: exactly 32 mm * Height: exactly 18 mm * Units: millimeters * Symmetry: perfectly symmetrical along the longitudinal centerline BODY DESIGN: * Classic Porsche 911-inspired proportions * Low and wide sports-car body * Rounded front hood * Smooth curved front bumper * Sloping windshield * Rounded roof * Smooth rear engine-cover area * Pronounced but simple wheel-arch shapes * Clean continuous exterior surfaces * Realistic automotive proportions SIMPLIFICATION FOR CNC: * Single solid body * No interior * No seats * No dashboard * No steering wheel * No mirrors * No door handles * No logos or text * No tiny decorative details * No extremely thin walls * No sharp unnecessary edges * Avoid complicated undercuts * Avoid deep cavities * Keep all surfaces accessible for a 3-axis CNC machine * Use smooth NURBS/freeform surfaces where necessary * Keep the geometry lightweight and computationally simple * The model must be suitable for roughing with a 10 mm end mill GEOMETRY QUALITY: * Watertight solid * No holes * No self-intersections * No duplicate surfaces * No disconnected bodies * Smooth tangent transitions between major surfaces * Accurate dimensions * Clean CAD topology * Manufacturing-ready solid model OUTPUT: Generate a true editable CAD solid. Export as STEP (.STEP/.STP). Do NOT generate an STL mesh. Do NOT generate an image or rendering. The final result should clearly resemble a miniature Porsche 911-style sports car while remaining simple, clean, symmetrical, and practical for CNC machining.
Parameters
| Name | Value | Range |
|---|---|---|
| Length | 55 mm | 40 – 80 |
| Width | 32 mm | 20 – 50 |
| Height | 18 mm | 10 – 30 |
