I've made a 235c silicone sleeve to help the nozzle retain heat and keep the fan air cool. Works well so far and I've just orderd a 300c silicone to help extend the life of the sleeve. I will be selling them for $1 a piece + shipping. I have a sign up sheet if you're interested. Also someone created a Germany signup sheet to help save on shippping...the link is also on my sheet. THanks!!
