The prompt
clear the part and redesign it with "Create a solid parametric horizontal inline-3 engine block out of 6061-T6 aluminum. Total external dimensions must be 189.0 mm width (X-axis), 111.5 mm length (Z-axis), and 102.0 mm height (Y-axis). Bore three parallel, horizontal cylinders cleanly through the width of the block. The left cylinder bore is 43.0 mm diameter centered at X=36.5mm. The right cylinder bore is 43.0 mm diameter centered at X=152.5mm. The central cylinder bore is 57.0 mm diameter centered at X=94.5mm. The center axis of all three cylinders must sit precisely 43.5 mm from the front face of the block. Along the rear wall, extrude a continuous horizontal pushrod tunnel cavity measuring 12.0 mm deep, starting exactly 80.0 mm from the front block face, leaving a 28.5 mm solid aluminum separation wall between the cylinder axis and the tunnel.
