Ender 3 Mainboard Fan Guard
thingiverse
Updated mainboard fan cover / duct for Creality Ender 3. This one covers the mainboard cooling fan, but instead of the air intake pointing towards the user (and still under the bed), this model moves the intake to the leftmost edge of the frame. The V grooves in the left side of the base are covered so as to avoid sucking stray filament from the grooves into the fan. This cover should reduce print issues due to uneven heating / cooling of the print bed. Earlier block style model replaced with rounded right side. Model updated to remove crossbars at the fan intake, and to fully enclose the shroud.
