Insulation of the heater barrel
There's a good alternative to glass fiber wool, a material I wanted to avoid. It will give you an itchy skin because you have a lot of small cuts from the glass. What I did differently, I cut a rectangular piece out of a 'silicone baking mat'. You can find these in a cooking store or various other places. It can handle high temperatures (above 300 without any problems, I guess) and it's very rubbery. It can hold everything together very easily and it can be removed as well (as opposed to fire cement). It doesn't have much specific heat, so the extruder will heat up (or cool down) quickly, because only the copper needs to get very hot.
