Replicator extruder cooling fan exhaust nozzle

thingiverse

Initially, I aimed to create a visually appealing design with curved shapes, but it surprisingly offers a minor advantage. As the nozzle narrows, airflow is accelerated, while refining the central fan area's contour reduces drag. The primary benefit appears to be reduced noise. This modification is particularly suitable for the reversed fan mod. For printing, avoid using raft or supports and ensure you have longer M3 screws (45mm) for proper fitment.
