Cool E3D Tevo Tornado

You can print PETG, but ABS is better. Due to the correct position of the blowing nozzles, the air flow falls directly under the hotend nozzle, without affecting the stability of the hotend nozzle heating. In this model, the airflow used a basic cooler. It is necessary to buy another turbine cooler.
Now it is possible to print without supports and print long bridges without sagging plastic.
