EDIT October 2021 - Several comments about the fit of screws and the like on this recently - the design is almost 3 years old at this point, and the printer I made it for was shipped in winter 2018. Given how 3d printer companies tend to iterate things all the time, it's pretty likely that the PSU they use now isn't exactly the same as they were using when I designed this.
I make no claims on the accuracy of fit on a currently shipping Ender 3 / Meanwell PSU. You can always download the files and check the dimensions before printing.
No updates planned for this design unless I have to replace my PSU.
Very simple remix of the [Ender 3 Power Supply Fan Silencer](https://www.thingiverse.com/thing:3328495) by [Eigengrow] (https://www.thingiverse.com/Eigengrow/about) so that it fits the Ender 3 Pro Meanwell power supply. I printed off a few layers from his original design to check the size, and it worked, but had to be flipped since the Meanwell PSU screws are oriented differently than the original Ender 3 PSU. Used tinkercad to flip the design and printed it off with the channels facing up to minimize how many supports were needed and it fit just fine. Redirects the air toward the back instead of off to the side and reduces the noise pretty well without significantly impeding airflow.
Just like in the Eigengrow's version, the holes are undersized for the fan screws, but that means you can carefully drill them out to fit (I was able do so by hand, just twisting a bit…
