The prompt
That did not work please build this one "Create a solid rectangular block out of 6061-T6 aluminum with a bounding box of X=189.0 mm width, Y=102.0 mm height, and Z=111.5 mm depth. Set the origin datum (0,0,0) at the bottom-front-left corner. Cut three parallel, cylindrical cylinder bores extending completely through the block along the Z-axis from Z=0 to Z=111.5 mm. The Left Cylinder bore has a diameter of 43.0 mm, with its center axis located at X=36.5 mm and Y=43.5 mm. The Central Cylinder bore has a diameter of 57.0 mm, with its center axis located at X=94.5 mm and Y=43.5 mm. The Right Cylinder bore has a diameter of 43.0 mm, with its center axis located at X=152.5 mm and Y=43.5 mm. Along the rear edge of the block face, cut a continuous rectangular pushrod tunnel cavity extending completely through the block from Z=0 to Z=111.5 mm; this cavity has a width of 12.0 mm along the Y-axis, spanning from Y=80.0 mm to Y=92.0 mm, and spans the full width of the X-axis from X=0 to X=189.0 mm."
