The prompt
Generate a 3D parametric mechanical hub for a 3V geodesic dome. Base body is a regular circumscribed hexagon plate, 160mm across flats, 8mm thick. The hub features 6 equally spaced radial connector legs branching outwards at 60-degree increments from a central axis. Each leg must be structurally tilted downward by a dihedral angle of exactly 11 degrees relative to the flat top surface of the hex plate. Each leg consists of a U-shaped dual-flange channel designed to slide over a rectangular aluminum strut profile measuring 40mm wide by 20mm high. Inside the center floor of each channel, add a raised alignment rectangular key/tongue profile 8mm wide and 3mm tall running along the channel length. Add two vertical through-holes for M6 bolts on each leg channel, spaced 25mm apart along the centerline. Add an explicit clearance tolerance offset of 0.15mm to all internal pocket walls. Export as an editable STEP file.
