The prompt
Design a 65 mm diameter miniature turbocharger display model consisting of 12 separate mechanically assembleable parts. Include compressor housing, compressor cover, center cartridge, turbine housing, turbine cover, compressor wheel, turbine wheel, main shaft, 2 mm DC motor coupler, motor mount, front retainer and rear retainer. Use 0.4 mm minimum wall thickness and 0.45 mm running clearance for PLA. The compressor and turbine wheels must mount concentrically on the shaft and rotate freely. The motor mount must accept a small 3–6 V DC hobby motor with a 2 mm shaft. Make every component a separate solid body and ensure all bodies are watertight and exportable as individual STL files
