Bear-BMG Fusion Dual Fan Duct
Description
UPDATE 2/21: I have uploaded a V2 of the duct that lowers it by 1.25mm to improve cooling and less direct air to the nozzle. I have also cleaned up some defects in the v1 duct work. The Bear BMG fusion extruder by MarcoZ76 has been an amazing upgrade for my MK3 but my part cooling was lacking. Jonathanrswift created a great dual fan duct for multiple MK3 extruders but none fit the fusion extruder properly so I remixed the design to fit. Here are the changes to the design: - Shifted the upper screw hole down to match the cover from the fusion extruder - Moved the right fan further out as it was hitting the motor - Had trouble printing the ducts in polycarbonate due to the flat ceilings of the ducts so I thickened them a bit and added some slope
