40mm fan mount for the All-Metal E3D v6 Hot-End to Velleman K8200/3Drag standard filament extruder.

Fan duct snap on reusing original extruder screws and spacers, optimized for robustness and easy print.

This is a remix for 40mm fan of K8200/3Drag E3D v6 HotEnd extruder mount with fan.

The 40mm fan is more quit than the standard 30mm standard.
I just ordered the Noctua NF-A4x10 FLX 40mm fan with noise level below 18dB(A), but there are other solutions out there...

Please post your experiences with this fan duct.

Update: Added STEP model for easier remix.
