I just tried it out on the extra cable I had and I think I'm going to just do this for all of em. I cut it every 4 wires.
Then I'll wrap it in some of the braided sleeves and put heat shrink on the end. The thickness is like .35" when they are stacked that way so I'll go with the 1/2" braid.
Anyone have any suggestions on how to make a cleaner looking cover for the part where the wires meet the connector? Like on the professional ones it has a nice transition covering that part. Maybe I could get some 2" heatshrink and use that on the ends but then it would have to shrink down 4x to cover the edges of the 1/2" sleeve. I've seen a bunch of 3:1 stuff when searching amazon but not sure if I saw 4:1 stuff.
