Blower Fan Duct for Dual Extruder Cooling for Flashforge Inventor 3D Printer

thingiverse

This blower fan duct was designed to interface seamlessly with the Flashforge Inventor 3D printer, providing consistent cooling to both installed extruders. A smooth path redirects air flow directly to the forward tips of the extruder nozzles, ensuring evenness of the cooling process. The effectiveness of this design was tested by running tap water through the intake and observing the flow coming out at the slotted ends, yielding impressive results. However, this blower fan duct is still a work in progress as test prints are being made to assess its actual cooling performance. If it fails to meet expectations, the tilt of the slots can be easily adjusted for optimal performance. Other notable features include: - The M3 screw hole has been deepened, significantly reducing the likelihood of the screw falling off during installation. - Air flow is barely restricted at the intake, allowing smooth passage prior to compression at the bottom. - The air path at the bottom maintains relatively wide turning angles with a straight last segment, directing air directly toward the nozzle instead of diagonally. - Once installed, it does not obstruct the extruder carriage from traveling to the left and front extremities, ensuring the door still has sufficient clearance to operate. - Plenty of clearance is provided around the aluminum blocks to minimize deformation caused by radiated heat. - Easy to print, requiring only external supports on the exterior when printed vertically. A .fpp file with required external supports is included. The design also facilitates the printing of internal bridges for a smoother duct ceiling.
