3d bust model

Highly realistic 3D printable bust of a young man in an elegant suit, based on the reference image, preserving accurate facial likeness and proportions. All parts must be fully merged into a single continuous volume. No gaps, no intersections, no separated geometry. Hands, hair, head, neck and clothing must be fused together as one solid body. Hair must follow the head surface as shallow relief only, no volume, no protrusions, no layers, no extensions outside the silhouette. Contact areas (hands touching face, hair, neck) must be physically joined and blended, not intersecting or floating. All details must be embedded as surface relief, never detached. Back closed and smooth. Solid watertight mesh, no holes, no hollow parts. Optimized for FDM printing: self-supporting geometry, no unsupported gaps, no support-heavy structures.
