I like the nozzle light and that i have a source of power without the need of having to run a extra cable to the carrier. But i also had 2 problems: the printer stands to the left of my desk, i cant see the light and the secound is the fan, its very powerful but also very noisy.
So i made a transparent case where i can see the lights better and where i can put in a small dc to dc converter to adjust the fanspeed down. Now when the printer runs i cant hear the fan but its still providing enough airflow to keep the Extrudermotor cool.
