Description
This is meant to keep the barrel and extruder inlet cooler so the filament doesn't melt to early and cause a jam.
The duct slides right in on the extruder housing. If the fit is tight enough, it may stay; otherwise, super glue or something will hold it in place. Some light finish work may be required to make it fit nicely.
I simply glued the 40mm fan on the duct intake.
The fan runs on an external 12V source so that it remains on.
