The prompt
"A precise 3D CAD model of a closed centrifugal pump impeller with an outer diameter of 169mm and a total height (H) of 139mm. Top side features an integrated long cylindrical guide shaft with an outer diameter (ds) of 68mm and a shaft height of 116mm. Inside the hollow shaft, with an inner diameter (di) of 61mm, there are exactly 6 radial internal wedge-shaped splines/ribs. These ribs reduce the inner clearance diameter (dr) to 41mm; each rib is 14mm wide at the shaft wall base and tapers down to 2.5mm at the inner tip. The impeller body has a flat top shroud plate with a thickness (b) of 7mm, an internal channel height of 9mm, an outlet channel width of 52mm, and a suction eye inlet diameter of 41mm on the bottom side. Clean technical geometry, suitable for STEP or IGES."
