Ender 3 Board Low Profile Fan Shroud
thingiverse
A simple yet effective fan shroud for the main board of the ender 3. Since I recently installed a 3Dfused y axis linear rail kit, I had less space between the bed knobs and the board case, so I made a shroud that is low profile. I also think that the shroud being designed this way is less restrictive for the fan that other duct type shrouds.
