The prompt
Generate a 3D parametric mechanical 5-way connector hub for a 4V frequency geodesic dome structure. The central core body is a regular circumscribed pentagon plate with a flat top face, measuring 160mm diameter across flat sides, and 10mm thick. The hub features 5 equally spaced radial connector legs branching outwards at 72-degree increments from the central Z-axis. Each leg must be structurally tilted downward by a dihedral angle of exactly 7.6 degrees relative to the flat top surface of the pentagonal plate. Each leg consists of an open U-shaped dual-flange channel designed to slide over a custom aluminum T-slot extrusion profile measuring 40mm wide by 30mm deep. Centered inside the floor of each channel, add a raised longitudinal alignment tongue measuring 10mm wide and 4mm tall. Each leg channel must include two through-holes for M6 bolts spaced 30mm apart along the centerline. Apply a +0.15mm tolerance clearance to all internal pocket walls.
