soccer shin guard 3d model

Model a realistic soccer shin guard plastic shell (only the rigid outer part, not the foam). Use these specs and references: Shape: Curved ergonomic shell following tibia shape. Smooth front surface with vent holes. Dimensions (size M): Height 185 mm, width 90 mm, curvature depth 15 mm, plastic thickness 2.5 mm. Curvature: Along the vertical axis, the guard should gently curve inward forming a radius matching a human shin (~15 mm offset from flat plane at center). Surface: Smooth outer side with slightly rounded edges. Holes: Add 8–12 ventilation holes in two vertical rows (like in Puma shin guards). Material: Hard glossy thermoplastic (e.g. polypropylene). Color white. Back side: Concave shape that fits the shin’s contour (no foam padding). Style reference: Puma UltraLight / evoSPEED style — aerodynamic, slightly asymmetric top and bottom. Output format: STL or OBJ, centered at origin, real scale (mm), single watertight mesh.
