Prompt

Make a finned block. Base: a rectangular plate 50mm long (X) × 30mm wide (Y) × 5mm thick (Z), centered in X and Y, with the bottom face on the XY plane (z = 0 to z = 5). Three rectangular fins stand on top of the base, each 50mm long in X, 3mm thick in Y, and 15mm tall in Z (z = 5 to z = 20). The fins are centered on y = -10, y = 0, and y = 10 (each fin spans 1.5mm to either side of its centerline). Output a single solid.
