The prompt
A 3D CAD model of a rectangular HVAC duct blast gate damper (ventilation slider valve) consisting of 3 separate interlocking plastic parts, designed for a 204 mm * 60 mm rectangular ventilation duct. Key specifications: Main Body (2 identical halves / flanges): Rectangular sleeve connection port on both sides matching outer dimensions of 204 mm * 60 mm ducting. Wide perimeter mounting flange with uniformly spaced screw holes around the border (10 thru-holes total). Internal channel and a small gap slot for an airtight rubber/gasket seal around the sliding blade. Sliding Gate (3rd part): Flat rectangular sliding blade damper plate that inserts into the side slot. Features an ergonomic pull handle / end lip on one end to adjust airflow manually. Style & Finish: Clean mechanical CAD design, smooth white plastic finish, modular assembly, precise dimensions suitable for 3D printing and bolting together.
