Ender 3 V2 Silent PSU

This is a remix of the awesome design by sectorone. [Check out my Ender 3 V2 Silent Motherboard and complete the set!](https://www.thingiverse.com/thing:4549738) My remix houses an 80mm x 10mm fan that sits completely flush with the inside of the power supply cover. [The 80x10 Fan that I'm using](https://www.amazon.com/gp/product/B07ZC4LNNY/) The fan bulge protrudes 8mm below the power supply and your Ender 3 v2 should have 12mm of under-side space available. This makes it a tight fit with 4mm of space for air to travel through. After much deliberation, I positioned my fan to blow air into the power supply to match the configuration of the stock fan. I've revised this thing several times, make sure you get the latest file. Note that this thing needs to be printed vertically and rotated at a 45deg angle in order to fit on the ender 3 bed. The fan grill is printable in the vertical orientation - do not put supports in it, you will break it! Print with a raft and regular "supports everywhere" but block supports from being generated in the fan grill and all of the vertical fan and ventilation holes. Take your time and do a good slice and your print will come out great, no prob. PS: The PSU fan pins are reversed! Make sure that your replacement fan pins match the polarity of the original fan! You will probably have to switch the pins around. *** UPDATE: If the fan is going to be blowing air in, you will need to cut out the grill because the fan will lift during rotation and scrape against the grill. If you're positioning the fan as an exhaust fan (not the factory configuration!) then you can leave the grill in place. There's just not enough clearance for me to move the grill further out, sorry!
