This is a remix of the Heated Bed Cable Chain from NedalLive. I modified it to go from the bed to the bottom extrusion. The bottom frame mount replaces a corner brace for the 3030 extrusion as well as redirects wires from chain to electronics enclosure. The upper cable chain mount attaches to the 2020 bed frame, it was modified for length to match where the bottom was. My Hypercube is 300x300x400 and it took 36 pieces of chain to go from bed to base.
