This is a folding leg hub designed for a 4‑leg portable stool.
It acts as the central joint, connecting all four legs and allowing smooth folding and unfolding.
The part is optimized for 3D printing, with reinforced geometry, easy‑to‑assemble screw points, and a compact structure suitable for outdoor or photography stools.
Ideal for replacing broken hubs or building custom lightweight folding stools.
