Prompt

Make a hex-head bolt blank as a single solid with no holes. The hexagonal head is a regular hexagonal prism with flat-to-flat distance 24mm and height 14mm, base on the XY plane (z = 0 to z = 14), centered on the Z axis, oriented so two flats are parallel to the X axis (flat-to-flat distance 24mm in the Y direction, so the head spans y in [-12, 12] and x in [-13.856, 13.856]). Directly above the head and concentric with it is a cylindrical shank of diameter 14mm and height 46mm (z = 14 to z = 60). The combined part is a single solid: hexagonal head at bottom, cylindrical shank extending upward. Output a single solid with no bores or holes.
