Ender 3 PSU fan cover

thingiverse

<b>Update 3:</b> During a 3-hour printing session, the temperature of air coming out of the PSU with cover mounted reached 30 degrees Celsius while room temperature was approximately 23 degrees. Printing without the cover resulted in temperatures about 1-1.5 degrees lower, but this could be attributed to thermometer probe placement. Overall, I would conclude that it does not significantly impact the fan's performance. <b>Update:</b> A concern has been raised that removing the cover might reduce airflow too much and increase temperature on the PSU. Fortunately, it doesn't seem to slow down the fan, but this project remains "Work in progress" until further testing is conducted on its effects on the fan's performance. Air duct cover for Ender 3 PSU (or any compatible power supply) primarily designed for noise reduction. It directs the air coming out of the supply towards the back of the printer. Mounted using double-sided foam tape. Print vertically with brim for better adhesion to prevent ends from curling up. Takes approximately an hour to print with 0.2 layer height. <i>Note: The Fusion360 design file is named _v2, but both files contain the same model.</i>
