For those who Crochet.
started with a magic loop and sc 6. Then just went round and round till it was long enough, made a very long single chain and joined.
I used varigated crochet thread leftovers, and a D hook (I think thats 3.25mm)
Sell them on Amazon. You'll make a mint. There's ecigs all over the place there now. Just list which models they fit, which looks like about all of them.
