Bear-BMG Fusion Dual Fan Duct
thingiverse
UPDATE 2/21: I've uploaded V2 of the duct, reducing its height by 1.25mm to enhance cooling and minimize direct air flow to the nozzle. Additionally, I've corrected several defects in the original v1 duct work. The Bear BMG fusion extruder, courtesy of MarcoZ76, has significantly improved my MK3 setup, but part cooling remained a challenge. Jonathanrswift's dual fan duct design for multiple MK3 extruders was inspiring, but it didn't fit the fusion extruder properly. Therefore, I adapted the design to make it compatible. Key modifications to the design include: - Lowering the upper screw hole to align with the cover of the fusion extruder - Extending the right fan outward to avoid interference with the motor - Thickening and adding a slope to the flat ceilings of the ducts due to printing difficulties in polycarbonate
