The prompt
Create a 3D rigid flange coupling with the following dimensions in millimetres: - Flange outer diameter: 100 mm - Bolt circle diameter (PCD): 90 mm - Bolt holes: 4 holes, each 12 mm diameter, equally spaced at 90° intervals - Hub outer diameter: 45 mm - Shaft diameter: 20 mm - Flange thickness: 10 mm each - Two mating flanges with central hubs - Two aligned shafts passing through the central bores - Include 4 bolts and nuts to connect the flanges - No keyway or key slot Make the model symmetrical, with both flange faces touching and all bolt holes aligned. Keep the shaft and central bores concentric. Use a metallic grey appearance. Generate a clean, accurate 3D solid model suitable for mechanical engineering CAD. Use millimetres for all dimensions. Make all components cylindrical and properly aligned. Do not add unnecessary features. Export the final model as a STEP (.step) file, with an STL file if available.
