human face 3d model

A photorealistic, high-poly 3D scan of a human face, neutral expression, closed mouth, eyes forward. The mesh must be completely watertight, manifold, and solid with zero holes, gaps, or non-manifold edges. Extreme high resolution mesh detail suitable for import into CAD software like CATIA and SolidWorks for further modification and engineering. 3D model, clean topology, quad-based mesh, OBJ or STL format, isolated face on black background.
