I used this:
Ebay # 291843905734.
Had lots left over , can do quite a few rollers.
To wrap properly you need someone to hold the roller and slowly rotate
it while you maintain tension on the Kapton tape reel for a firm bond
with slightly overlapping continuous feed to accomplish the wrap. Much
like winding an electromagnet.
