The prompt
Generate a solid parametric 3D CAD model of a mechanical pressure vessel. Main body: Vertical hollow cylinder, OD 50.8mm, ID 44.8mm, height 152.4mm, wall thickness 3.0mm. Interior: Concentric cylindrical chamber with a 1.5mm recessed annular ledge at z=3mm and z=149.4mm for holding mesh filter discs. Inlet base: Perforated diffuser plate with 12 radial 1.5mm thru-holes. Caps: Both ends feature female 1/2-inch NPT threaded fittings. Valve housing: Integrated 90-degree transverse cylindrical bore with two internal 2.0mm O-ring grooves for a rotary bypass valve. All geometry must be manifold, solid B-Rep, and watertight.
