The prompt
Can you work on the mechanical design of our continuous-flow centrifugal pump? Start by designing the pump housing, inlet/outlet, volute, and 6-blade impeller around roughly a 50 mm overall pump size. Make the CAD parametric so we can easily change things like impeller diameter, blade angle, blade height, hub diameter, and clearances. The pump should be designed for a closed-loop blood-analog fluid, not actual blood or use in a person. Also look into how we could integrate the magnetically levitated rotor, including the permanent magnets, electromagnets, position sensors, and motor/stator while keeping the fluid chamber sealed. For now, focus on the CAD and mechanical dimensions and give me the measurements, materials, tolerances, and any problems you run into so we can use them for CNC machining later. Only make the pump part, worry about the outer housing later
