The prompt
1. Base Plate (Inlet): Dimensions: 120mm x 240mm rectangular footprint with a 6mm thickness to prevent warping during ASA printing. Cutouts: Two side-by-side circular openings matching the dual 120mm fan layout. Mounting & Gussets: Four corner screw holes featuring raised cylindrical bosses connected to the main shroud body via angled reinforcement ribs, aligned as shown in the corner reference view. 2. Duct Output (Outlet): Diameter: 151mm outer diameter circular opening. Retention Lip: Continuous raised exterior bead near the upper rim to secure a hose clamp. 3. Transition Body (Loft): Length & Wall Thickness: Maximum 95mm transition height with a minimum 4mm uniform wall thickness. Geometry: Smooth internal aerodynamic loft merging the dual base cutouts into the single top outlet. Maintain self-supporting overhang angles for upright FDM printing without internal supports. Deliverables: Watertight .STL and .STEP files.
