eye globe 3d model

"Technical 3D model for medical simulation: A 24mm diameter hollow sphere with a uniform 1.5mm wall thickness. Anterior center features a 12mm diameter cornea, raised 1.0mm from the surface to define the limbal ring. Anatomical landmarks: Four horizontal debossed grooves, each 5mm wide and 0.5mm deep, positioned at precise offsets posterior to the corneal limbus: 5.5mm (Medial), 6.5mm (Inferior), 6.9mm (Lateral), and 7.7mm (Superior). These grooves serve as muscle insertion guides. Posterior pole features a mechanical pivot assembly: a 5mm diameter spherical ball-joint mounted on a 3mm long, 4mm diameter cylindrical neck centered at the back of the globe. The model must be manifold and watertight for 3D printing. Surface finish: Matte, non-reflective PBR texture. The geometry must prioritize dimensional accuracy over organic smoothing. No eyelids, eyelashes, or skin structures included. Optimized for SLA/FDM printing with a focus on structural rigidity at the neck and clear definition
