Meanwell SE-450-24 120mm Fan Cover

So I made a BLV MGN Cube (Thanks Ben Levi!) and got a genuine Mean Well 24V 450W power supply for it. The stock fan was loud though, so I replaced it with a Noctua A6x25 fan. Although quieter, the Noctua fan still turned out to be pretty loud, and remained the loudest part of the printer while idle. So, I swapped it out for a 120mm fan instead. I chose 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 my other non-special cooling fans audible, even when not running at full power, which is quite surprising. I also added labels to the ports of the power supply on the bottom to match the case's indications. To get + on the V+ created nicely without slicer support, I had to use a sacrificial layer. I was able to print everything without needing support then. Next, I put the Mean Well logo on the cover to show it off as a genuine Mean Well power supply. However, I included a version of the cover without the logo in case someone didn't want it there. I'm not affiliated with Mean Well, but their power supplies are pretty good. I've included the STEP files just in case anyone wants to change something like the positioning of the mounting holes. Honestly, I'm planning on using mightynozzle's fan covers from https://www.thingiverse.com/thing:2802474 because they're already well made. To attach the cover, I reused the stock screws and the screws that came with the fan. Currently, 2 of the fan screws are attaching the fan, and I'll be using the other 2 screws to attach the cover to the fan. Update 12/18/2019: I added files including half the logo - just the 'MW' without the 'Mean Well' text. Also, from my experience with this setup, the extra cooling provided by a larger fan makes up for the fact that the printed cover is not metal. When I felt the metal casing of the PSU during a print, it was cooler with the 120mm fan compared to feeling it with a Noctua A6x25 fan running on the metal cover. As a note for people looking to use another 120mm fan they have or bought, make sure it can run at 12V, as that's 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 a lower voltage fan, you would need to use something like a buck converter to lower the voltage.
