2020 Five-Way Lattice Hub
A five-way socket hub for 2020 aluminium extrusion. Four horizontal rails and one vertical rail meet at a single node, so you can build 3D box frames and rover cages instead of flat rectangles. Each 20.4 mm socket is 20 mm deep and has 3.5 mm walls, with a 5.5 mm M5 clearance hole centred on every slot face for standard M5 T-nuts. A counterbored M5 hole runs up through the core for an end-tap bolt into the vertical rail. The hub is 67.4 mm across and 47.4 mm tall.
