The prompt
Create a simplified solid 3D model of a human skull and spine, external surface only. Skull: one solid cranium shape with eye sockets, nasal opening, cheekbones and a separate lower jaw. No teeth, with a smooth flat alveolar ridge on the upper and lower jaw. Spine: 24 stacked vertebrae (7 cervical, 12 thoracic, 5 lumbar) plus sacrum and coccyx. Each vertebra is a solid body with a spinous process at the back and two transverse processes on the sides. Place a thin disc spacer between each vertebra. Give the spine its natural S-curve, with the skull resting on the top cervical vertebra. Make everything fully solid with no internal cavities, no hollow interior, no sinuses and no spinal canal. Exclude ribs and soft tissue. Output as a single watertight solid, STEP/STL.
