FlyingBear Ghost Fan Air Duct Model Improved

Individually designed, improved air duct for airflow during printing. Created for my printer FlyingBear-Ghost. According to my observations, the airflow of the model has improved, but without changing the fan, cooling is moderate, with warm air due to the design features of the original extruder block. I printed it with ABS filament, followed by smoothing with methylene chloride (or acetone can be used).
