How to attach insulation to Hot End I bought some heating block cotton to insulate the exposed surface of my hot end.  I thought the yellow as double-sticky but it appears to be Kapton.

What can I use to attach it to the extruder?



My extruder is already covered on four sides.  I want to cover the other two.
Kapton tape would be the logical material. It's unfortunate that your vendor did not supply that as a separate item, rather than sticking it to the "cotton" (I'm guessing not actually cotton, as things might get a bit scorching for cotton, so I'm assuming some type of ceramic fiber or the like.)
