hand 3d model

Photorealistic highly detailed human hand, anatomically correct proportions, realistic skin surface with natural wrinkles, knuckle details, fingernails, and subtle vein texture. The hand is positioned like the hand of Adam in Michelangelo's Sistine Chapel ceiling — arm slightly extended, wrist relaxed, fingers naturally and gently outstretched as if reaching toward something or offering. The hand rests on the back of the hand and wrist, tilted at approximately 20 degrees, stable and self-supporting on that surface. Single solid mesh, no cuts. Neutral expression, adult male hand. 15cm long from wrist to fingertip. Export as a single STL file optimized for FDM 3D printing with black matte PLA.
