The prompt
Create one simple parametric steel mounting crossbar. Do not create an assembly. Do not create posts, hooks, bearings, shafts or handles. The part is a flat rectangular steel bar. Exact dimensions: - length: 250 mm - width: 45 mm - thickness: 12 mm - all dimensions in millimeters Create two vertical through-holes for cylindrical posts: - hole diameter: 25.2 mm - distance between hole centerlines: 180 mm - hole centerlines are on the longitudinal centerline of the bar - distance from each hole center to the nearest end of the bar: 35 mm Create one central mounting hole: - through-hole diameter: 20.5 mm - located on the longitudinal centerline of the bar - located exactly halfway between the two post holes Add 2 mm fillets to all external rectangular edges. The final result must be one single solid rectangular bar with three through-holes: two Ø25.2 mm holes for posts and one central Ø20.5 mm mounting hole. Do not add any other geometry. Do not add dimensions that are not specified. Create top, front, side and isometric views.
