Made some protection for the thermistor.
Be careful with heat shrink near the heat zone. It might expand/catch.
@Salim_Arakani what the heck man? Stop spamming people. Reported.
Have often covered thermistor with heatshrink without any problems. it gets a little hard over time maybe depends on the heatshrink.
PTFE heat shrinking will be much safe when using near by heater block
