Prusa i3 MK3(S) (+ MMU V2) Extruder Cooling Fan Duct

thingiverse

I've added two versions for MMU users based on CAD models of the MMU version of printers. These designs are created to ensure precise fit, so I can confirm their accuracy. This design is a revised version of CG-Tech's original concept. The main modification here is that the cooling duct is now integrated with Prusa's own filament sensor cover. This innovation allows you to mount the extruder cooling duct using a bolt instead of superglue. To complete this project, you will need a 5V fan to cool the extruder stepper motor. For more information on how to wire the fan, please refer to CG-Tech's post. Print the part in the orientation as shown in the .STL file. Some support material may be required for the filament sensor cover part, but this should not cause any issues. I'd like to thank CG-Tech for their excellent design!
