The prompt
"Create a solid parametric horizontal inline-3 engine block out of 6061-T6 aluminum. Total external dimensions must be 189.0 mm width, 111.5 mm depth, and 102.0 mm height. Bore three parallel, horizontal cylinders through the width of the block. The left cylinder bore must be 43.0 mm diameter. The right cylinder bore must be 43.0 mm diameter. The central cylinder bore must be 57.0 mm diameter. The distance between the centerline of the central cylinder and either outer cylinder centerline must be exactly 58.0 mm. Along the rear wall, extrude a continuous horizontal pushrod tunnel cavity measuring 12.0 mm deep across the full width."
