Alfawise U20 cable chain under the bed

thingiverse

Those are two simple adapters designed to conceal the bed cable chain under the bed. They're built for a 7x7 chain with an outside section measuring about 14x10 and a 4mm pin. Both can hold on their own without any additional support. They work, but aren't optimized. The bed part has a flat wire rail that guides wires to the bed connector. The bed adjustment bolt is sufficient to firmly hold the part to the moving platform of the bed, and the wire guide can hold wire by itself. There's also a second hole useful for securing everything together with a little cable tie. The frame part can be attached to the frame by turning the hook 90° counterclockwise inside the frame.
