BMG Extruder / Dragon High Flow Blower Fan Duct
thingiverse
This attaches to a standard 4020 Blower Fan for use with a BMG / Dragon High Flow Hot End combination. The 4020 Blower Fan attaches to the BMG extruder through the use of an adapter plate (see my BMG Extruder Blower Fan Adapter Plate), and (3x) M3 45mm hex head screws. Updated 07/30/2020: Updated in conjunction with the adapter plate to keep the air flow centered on the dragon hot end where it should be.
