wind turbine blade 3d model

Precise 3D model of a single isolated wind turbine blade, exactly 8 inches in total length. Realistic aerodynamic design with a modern airfoil cross-section: wider and thicker at the root, smoothly tapering to a narrow sharp tip, with a subtle aerodynamic twist along its length. From the flat root end, a perfectly centered straight cylindrical mounting hole runs lengthwise exactly down the middle of the blade: 0.25 inches in diameter and exactly 7.5 inches deep. Smooth seamless surfaces, clean manifold watertight geometry, high-resolution detail, optimized for 3D printing and manufacturing, professional engineering product visualization style, neutral gray color, no textures, isolated object.
