I'm wondering how to spool about 6ft of very thin wire into a small spool but always have it give tension, so if the wire is let go then it snaps back into the spool coiled. I'm thinking it has to do with a type of spring, but it would be great if the part was already available somewhere because its kinda intricate.Thanks! via /r/DIY http://ift.tt/2kmZuj4
