The prompt
"Generate a 3D parametric mechanical 6-way connector hub for a 4V frequency geodesic dome structure. The central core body is a regular circumscribed hexagon plate with a flat top face, measuring 180mm diameter across flat sides, and 10mm thick. The hub features 6 equally spaced radial connector legs branching outwards at 60-degree increments from the absolute central Z-axis. Each leg must be structurally tilted downward by a dihedral angle of exactly 8.2 degrees relative to the flat top surface of the hex plate. Each leg consists of an open U-shaped dual-flange channel engineered to cleanly sleeve over a rectangular aluminum T-slot extrusion profile measuring 40mm wide by 30mm deep. Centered inside the interior floor of each channel, add a raised longitudinal alignment tongue/key measuring 10mm wide and 4mm tall. Each leg channel must feature two vertically aligned through-holes for M6 bolts, spaced 30mm apart along the leg's centerline. Apply a global clearance tolerance offset of +0.15mm to all internal pocket faces for a sliding fit. Export as a solid parametric STEP file
