Vacuum Floor Head Lower Housing

Generate a 3D CAD model of a vacuum cleaner floor-head lower housing featuring an internal tapered suction manifold. Design parameters and geometry requirements are as follows: 1. Overall Footprint & Exterior: - Rectangular housing profile with smoothly rounded outer corners and ergonomic styling. - Approximate overall dimensions: Length (width across the floor) = 245 mm, Depth (front-to-back) = 110 mm, Height = 40 mm. 2. Floor-Facing Inlet Slot: - A continuous, narrow horizontal suction slot running along the bottom face near the front, spanning approximately 220 mm in length with a slot height of 6 mm. 3. Internal Tapered Suction Manifold (The Core Feature): - Design an internal air-collecting channel that connects the continuous bottom slot to a central outlet port. - The cross-sectional area of the internal channel must be at its minimum (narrow and shallow) at the outer left and right extremities of the floor head. - The channel cross-section must progressively and smoothly increase (taper larger in both width and depth) as it funnels inward toward the center, accommodating the cumulative volumetric airflow joining from the slot. - Symmetrical design flowing inward toward the exact center of the housing. 4. Central Outlet Port: - Located at the top-center of the manifold housing, a vertical circular collar/socket pointing upward, with an inner diameter of 32 mm, designed to connect to the upper suction duct. 5. Surface Finishes & Transitions: - Apply generous fillet radii (minimum 3 to 5 mm) to all internal junctions, corners, and floor-to-wall transitions within the manifold to ensure smooth airflow, prevent boundary layer separation, and eliminate sharp stagnation pockets. - Include standard mounting screw bosses and perimeter mating flanges around the top edge so it can assemble cleanly with an upper housing shell.
