This will allow you to print tall thin objects by directing all of the air flow to the tip of the nozzle. It allows you to use 13 mm overall length nozzles like CCTREE that are inexpensive and available from Amazon. This does not allow any airflow to hit the heater block so you will never get a heater failure no matter how high you set the fans. The air flow is so precise that I never go above 45% fan.
