The prompt
Create an accurate parametric 3D CAD model of B&R stepper motor 80MPD3.300S000-01 using the attached technical drawing as the reference. Units: mm. Dimensions: - Overall motor length L = 57.5 mm - Front flange = 56.4 × 56.4 mm square - 4 mounting holes: Ø4.5 mm (+0.3/-0) - Mounting-hole spacing: 47.14 ±0.2 mm horizontally and vertically - Central pilot: Ø38.1 ±0.05 mm - Output shaft: Ø6.35 mm (+0/-0.013), D-cut - Shaft length/projection: 20.6 ±0.4 mm - Shaft flat dimension: 15 ±0.25 mm - Front axial steps: 1.6 mm and 5 mm Keep all holes and circular features concentric/symmetric about the shaft axis. Reproduce the stepped front flange, D-cut shaft and motor housing geometry exactly as shown in the drawing. Use the attached drawing for any geometry not explicitly dimensioned above. Do not use the other motor lengths (45 mm or 80.5 mm). The required model is specifically 80MPD3.300S000-01 with L = 57.5 mm.
