About this 3D model
The design is a version of the great fan block from timmytool. It has some additional features like: - fan ejection nozzles on both sides of the MK7 heater. It provides more even airflow over the printing area and MK7 radiator; - wider ejection nozzles. Again, more air out - better cooling; - optional connection to additional air supply (compressor) for delicate prints.
