head mannequin 3d model

“A smooth human head 3D model shaped like a severed head (no neck stump details), with a straight vertical neck portion measuring exactly 150 mm in length. The head has no hair, no ears, and no facial features. The entire face area is carved out cleanly, forming a large oval opening when viewed from the front. The white area of the reference (outer surface) represents the carved-out face opening, and the beige area represents the outer head surface. The interior is hollow, thin-walled, seamless, and completely smooth like an empty shell. Remove all instructions for vertical elongation — the head should be a normal human head shape. All surfaces must be perfectly smooth with no textures, bumps, or anatomical detail. High symmetry, soft curvature, and minimal sculptural geometry. The face opening should have a smooth continuous edge and be slightly recessed inward. Don't worry about the dotted lines in the software.
