Just make your own, if u want to save a few bucks. I made my own with just a zip tie, tape and a razor. I got it off of tweakfiles' forum. --------------------------------------------------------------------------------
Ok to first make your homeade rounded cables you'll need:
A cable (duh!!)
Cable sheathing (as long as the cable, you can get it at any hardware store)
zip ties
a razor
and a pen
You'll need to first mark the spots that you want to cut, you need to cut in between the "rows" of wires.
so mark the spots>>>
Then you should put therazor on the spots you marked and not move the razor, but you should pull the cable up, along the rows.>>>
now you should stick your finger in between the cuts and pull along the length of the cable>>>
do this along all the cuts>>>
now fold all the ribbons together and zip tie them>>>
after you get all the zipties on (one every 3-4 of inches) start putting the sheath on>>>
Then when you get the cable alltheway into the sheath you can put zipties or electrical tape at the ends. but i find that the pressure of the sheath is enough alone.
your finished product!
