Ender 3 PSU fan cover

thingiverse

<b>Update 2:</b> During a 3 hour print the temperature of air coming out of the PSU with cover mounted reached 30 deg C while room temp was about 23 deg. Printing without cover the temperature was about 1-1,5 deg C lower, but this may be simply due to thermometer probe placement. Overall I would say it does not impact the fan's performance. <b>Update:</b> A concern has been raised that this may reduce the airflow too much and increase the temperature on the PSU. It doesn't seem to slow the fan down, but I've put this project as "Work in progress" until I do some further testing on its effects on the fan's performance. <hr> Air duct cover for Ender 3 PSU (or any compatible power supply). Mostly for noise reduction. 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 the ends from curling up. Takes about an hour to print with 0.2 layer. <i>Note: The Fusion360 design file is named _v2 but both files contain the same model</i>
