anatomical prop 3d model

Refine the existing 3D model for FDM 3D printing with selective color application and part separation. Part structure: - Head and teeth must remain a single combined part - Hair as a separate solid part with a clean plug-in or snap-fit connector - Eyes as separate solid parts (left and right) designed for press-fit insertion into eye sockets - Torso and base as separate parts (if applicable) Color and material rules: - Apply realistic skin tone color to the head - Apply natural white color to the teeth - Do NOT apply color to hair or eyes (they will be printed in separate filament colors) - No grayscale or clay material for the face Assembly requirements: - Head must include eye sockets suitable for inserting printed eyes - Hair must include a hidden connector that fits securely into the head - Proper tolerances for FDM printing (0.2–0.3 mm clearance) Technical requirements: - All parts watertight - Clean geometry - No intersecting meshes - Print-friendly thickness - Maintain reali
