A couple weeks ago, I placed an order on ebay for a few parts from China, and threw in some of this multicolor stranded-wire for less than a buck. It came in little plastic bags, so I decided to make some little spools for it so it'd be easier to get at.
To print the spools without supports, I designed each spool as two identical parts that snap together. Conveniently, the wire I bought came in rolls, so I was able to spool it without actually winding it. 😎
I also formatted the design so that it can be customized on Thingiverse before downloading; head over there if you want to try it out!
