The prompt
Generate a 3D parametric CAD model of a high-performance turbofan propeller with the following exact specifications: 1. Overall Dimensions & Layout: - Total Diameter: 5.7 inches (approx. 145 mm). - Central Hub: Cylindrical hub with a 22 mm outer diameter and a 10 mm overall height/thickness. 2. Blade Geometry: - Number of Blades: Exactly 15 blades. - Blade Profile: Swept, wide-chord blades featuring a progressive aerodynamic twist (angle decreasing smoothly from root to tip) optimized for high-RPM axial thrust and static pressure generation. 3. Motor Mounting & Center Bore: - Center Through-Hole: A clean cylindrical bore with a diameter of 5.2 mm running through the exact rotational center of the hub (clearing an M5 collet-style motor shaft). - Clamping Faces: The top and bottom exterior faces of the central hub must be perfectly flat, parallel to each other, and perpendicular to the rotational axis to serve as solid clamping surfaces for the collet flange and bullet nut. 4. Structural Reinforcement: - Root Fillets: Incorporate smooth transitional fillets (minimum 1.5 mm to 2 mm radius) along the entire internal junction where each blade root meets the central hub body to eliminate stress concentrations and prevent high-RPM fatigue cracking. 5. Output Requirement: - Output a clean, watertight, manifold solid geometry model free of self-intersections or non-manifold edges.
