The prompt
Create a dimensionally accurate 3D CAD model of a bushed-pin flexible coupling for an industrial water pump driven by a 2.2 kW, 1450 RPM motor. Units: mm. Dimensions: shaft Ø25 × 90 long; two hubs Ø50 × 38 long; two flanges Ø125 × 13 thick; flange gap 5; four Ø8 steel pins on Ø75 PCD; four rubber bushes Ø24 OD × Ø12 ID × 18 long; four brass sleeves Ø12 OD × Ø8 ID × 18 long. Include TWO SEPARATE removable parallel keys, each 8 × 7 × 32 mm, with matching keyways in both shafts and hubs. Create two separate coupling halves, two shafts, four pins, four rubber bushes, four brass sleeves, and two independent keys. Arrange all parts concentrically. Pins must connect the flanges through the rubber bushes. Do not fuse separate parts. Generate an assembled 3D model, exploded view, and dimensioned engineering drawing. Export STEP and STL if available. This is an educational CAD model, not a verified manufacturing design.
