Prompt

Make a hexagonal nut. The outer cross-section is a regular hexagon with flat-to-flat distance 19mm (so 19mm wrench fits), oriented so two flats are parallel to the X axis (the top and bottom of the hex). Height 8mm along Z, base on the XY plane (z = 0 to z = 8). Concentric central through-hole of diameter 10mm, axis along Z. Output a single solid.
