The prompt
A 3-piece ultra-low-profile modular rectangular HVAC blast gate damper (slider valve) for a $204\text{ mm} \times 60\text{ mm}$ rigid rectangular duct, optimized for maximum space-saving in tight vertical installations.Design Requirements:Duct Connection: The main housing consists of two symmetrical halves featuring internal sleeves that slip directly over the outside of the $204\text{ mm} \times 60\text{ mm}$ duct.No External Flanges / Screwless Design: Remove all traditional outer screw flanges and bolt holes entirely to minimize the external footprint and height.Tongue-and-Groove Assembly: The two housing halves must snap or slide together using a compact tongue-and-groove joint (interlocking slip-fit seam) along the perimeter, designed to be permanently sealed with foil/metal tape.Orientation & Travel: The sliding damper blade must pull out through the short edge (along the $60\text{ mm}$ side) to maintain a low profile. Include an internal slot with clearance for a thin airtight gasket around the sliding blade.Output format: Clean engineering CAD model optimized for FDM 3D printing (PETG), provided as 3 distinct components (Top Housing Half, Bottom Housing Half, Sliding Blade).
