Extruder fan air channel for Geeetech Prusa i3 MK8

thingiverse

If you own a MK8 extruder from Geeetech, then one thing's for sure - you'll need to add this. Attach it at the bottom of your extruder to redirect airflow from the fan to the build platform. Key Instructions Directly inspired by the original Geeetech MK8 extruder mount designed specifically for their Prusa i3 Acrylic 3D printer. Cut out the design supports within the print. Note: There is a small gap between the heatsink and air intake, an oversight in the initial design, but actually benefits from increasing airflow to the intake.
