Prompt
Make a long rectangular mounting rail 100mm long (X) × 20mm wide (Y) × 8mm thick (Z). Center it in X and Y, with the bottom face on the XY plane (z = 0 to z = 8). Drill three through-holes of diameter 6mm, axes parallel to Z, evenly spaced along the centerline (y = 0) at x = -40, x = 0, and x = 40. Output a single solid.
