Meanwell SE-450-24 120mm Fan Cover

So I made a BLV MGN Cube (Thanks Ben Levi!) and I got a genuine Mean Well 24V 450W power supply to use on it. The fan on it was loud however, so I got a Noctua A6x25 fan to replace the stock fan in it. Although quieter, the Noctua fan still turned out to be considerably audible, and remained the loudest part of the printer while idle. So, I went with a 120mm fan to replace that. (https://www.amazon.com/ARCTIC-F12-Silent-Ultra-Quiet-Configuration/dp/B0119T0D4I/) I went with the Arctic F12 Silent because it's cheaper than the Noctua A6x25 (Arctic F12 is ~$8 while the Noctua A6x25 is ~$15), is honestly overkill for cooling the power supply, AND IS COMPLETELY SILENT, BEING FAR MORE SILENT THAN THE A6x25 NOCTUA FAN. It makes the non-special cooling fans I have running, not even at full power, audible, which is quite shocking. I also put indications for the ports of power supply on the bottom to try and match the indications on the case. I had to use a sacrificial layer to get + on the V+ to be created nicely without support from a slicer,, able to get everything to print without support needed. I then put the Mean Well logo on the cover to show off that it is a genuine Mean Well power supply, though I included a version of the cover without the logo in case someone didn't want it there. I am not affiliated with Mean Well, but there power supplies are pretty good. I've included the STEP files just in case anyone is interested in or needs to change something like the positioning of the mounting holes. Honestly, I'm just going to get a fan cover from https://www.thingiverse.com/thing:2802474 because mightynozzle already made fan covers well. I just reused the stock screws to put the cover on, and the screws that came with the fan to put that on. Right now I have 2 of the fan screws attaching the fan on, and will be using the other 2 screw that came with the fan to attach the cover onto the fan. Update 12/18/2019: Added files including half the logo - just the 'MW' without the 'Mean Well' text.Also, from my use of this setup, the extra cooling provided from using a larger fan makes up for the fact that the printed cover is not metal. From feeling the metal casing of the PSU during a print, I felt it to be cooler with the 120mm fan compared to feeling the casing with a Noctua A6x25 fan running on the metal cover. Just as a note for people looking to use another 120mm fan they have or bought, make sure it can run 12V, as it is what the Mean Well PSU fan pins output. (Yes, despite the Mean Well SE-450-24 being a 24V power supply, the fan used in it is 12V) If you want to use lower voltage fan, you would need to use something like a buck converter to lower the voltage.
