This should work for most 6ft and smaller cables.
Examples are printed with 2 perimeters at .25 layer with a .6 nozzle. I would probably suggest 3 perimeters and use PLA+ or PETG for a more durable make in case of being dropped.
Should not need any supports, if there is, they should be minimal.
Will allow you to also keep excess cables from all over your design, doing essentially “roll your own length”.
