The prompt
A parametric 3D CAD solid model of a precision plastic linear hinge rail component based on exact engineering dimensions: 1. Primary Rail Dimensions: - Overall length: 304mm (Point 1) - Main body width: 38mm (Point 2) - Base thickness/height: 9.5mm (Point 10) - Structural side lip / groove width: 6mm with inner wall thickness of 5mm - Base side extension step width: 3.5mm (Point 12) 2. Side Cutout Reliefs: - Side notch depth: 7mm (Point 3) - Side notch total length along rail: 38mm (Point 4) 3. Center Hinge Assembly: - Integrated dual-ear hinge bracket located at the center of the rail - Outer bracket width: 35mm (Point 5) - Inner span / pin opening width: 36mm (Point 6) - Individual ear bracket thickness: 10.5mm per side (Point 7) - Hinge center offset projection distance from rail center: 24mm (Point 9) - Straight through-hole pin diameter: 8.0mm centered horizontally and vertically across both ears (Point 8) All edges feature functional 1mm fillets, and the pin holes have 0.5mm chamfers at the entries for assembly clearance.
