The prompt

Create a precision, parametric 3D cyclone dust separator for ANSYS Fluent CFD, in millimetres. - Cylindrical chamber: 100 mm internal diameter × 150 mm high. - Conical section: 250 mm high, tapering from 100 mm to 37.5 mm diameter. - Tangential inlet duct: 20 × 50 mm internal cross-section, 100 mm long, entering near the top of the cylinder. - Central vortex finder: 50 mm internal diameter, extending 50 mm below the roof. - Clean-air outlet pipe: 50 mm internal diameter, 100 mm long above the roof. - Bottom dust outlet: 37.5 mm internal diameter, with a 50 mm straight extension. Create a hollow, continuous internal fluid passage. Keep the inlet tangential, the vortex finder and dust outlet centred, and both outlets open. Make the geometry watertight and suitable for extracting a separate fluid volume in ANSYS SpaceClaim. Keep the dimensions editable. Avoid decorative details and unnecessary fillets. If possible, create named faces: "INLET_VELOCITY", "CLEAN_AIR_OUTLET", "DUST_OUTLET", and "CYCLONE_WALLS". Export as STEP.
