I made some improvements of the insulation. Main reason was to protect the thermo camera, but I used it also at another places. It is made from the so called “stove paper” which is 3mm thick and heat-resistant up to 1260°C. Its heat conductivity is also great: 0,07 Wm-1K-1 at 200°C. (upraveno)

I have also made shields for halogens allowing me to direct the heat towards print surface in the better way - halogen tube with shield can rotate in the r7s socket. You can see it in place in previous picture.
