The prompt
Create a rectangular block measuring 150mm width by 150mm length by 19mm thickness. On the top face, extrude a continuous closed groove tracking the perimeter, offset 10mm inward from the outer edges. The groove must be exactly 4.5mm wide and 3.2mm deep, with all four corners of the groove path filleted to a 12mm radius. Inside the inner boundary of this groove, pocket a shallow recess 2mm deep to act as a plenum chamber, leaving a 6mm flat border between the pocket and the groove. On the center of one side face of the 19mm block, add a horizontal blind circular bore hole measuring 6.2mm in diameter and extending 30mm deep into the block. On the top face, inside the plenum pocket, add a vertical through-hole 6.2mm in diameter that intersects cleanly with the horizontal side bore hole to create a continuous internal air passage. On the bottom face of the block, extrude two cylindrical indexing pins 20mm in diameter extending 10mm downward, spaced 96mm apart on center.
