The prompt
Design a professional parametric mechanical CAD assembly for a handheld one-hand assistive smart wound dressing dispenser. Overall Dimensions: Length: 90 mm Width: 60 mm Height: 55 mm Housing: - Two-piece enclosure (Top Cover + Bottom Base) - Wall thickness: 2.5 mm - Rounded corners (R8 mm) - Medical-grade ABS plastic - Internal screw bosses with M3 screws - Front dispensing nozzle - Rear removable cover for loading dressing roll Internal Mechanism: - Dressing roll diameter: 40 mm - Roll width: 50 mm - Stainless steel shaft diameter: 8 mm - Ratchet wheel with 20 teeth - Spring-loaded pawl mechanism - Compression spring: Length: 25 mm Outer diameter: 12 mm Wire diameter: 1 mm - Thumb-operated lever with 12° rotation - Lever pivot pin diameter: 3 mm Peel Mechanism: - Stainless steel peel bar - Peel angle: 180° - Separate path for silicone backing liner - Dressing exits from front slot - Backing liner exits downward into waste slot Cutting Mechanism: - Integrated serrated cutter blade - Cutter width: 55 mm - Blade positioned directly after dressing exit Motion: Each lever press advances dressing by exactly 5 mm. Ratchet prevents reverse rotation. Compression spring automatically resets the lever. Assembly: Generate individual parts and complete assembly. Include exploded assembly. Generate all components as parametric solids. Maintain manufacturing clearances of 0.3 mm. Include realistic fasteners. No electronics. Mechanical operation only.
