CR6 Max PSU Dual 80mm Fan Cover - MeanWell RSP-500-24

thingiverse

Not much to say here other than this is a replacement cover for the meanwell PSU that comes in the CR6 Max. It requires leaving the bottom cover off of the printer. If you're not comfortable with that, this one isn't for you. The fan cover has spots for two 80mm fans. I mounted them blowing in. The replacement 40x20 noctua at the back is mounted blowing out. I had anticipated needing a buck converter for the fans, but that turned out to be unnecessary because the Meanwell outputs 12v for the fans at the JST plug connection for the stock fan. I had already planned to reuse a housing for an LM2596 and 3 wire LED voltmeter that I had previously designed, and I still wanted the voltmeter to be able to monitor voltage to the fans, so I just kept the whole housing. The housing ended up being a convenient place to terminate the fan connections. If you don't care about having a voltmeter for the fans, then feel free to not print the buck converter and LED voltmeter housing pieces. Messing with electronics can be dangerous. Do this at your own risk. Even unplugged, there is still significant voltage and amperage potential from the PSU due to the capacitors. If you screw this up, you could die, fry your fans, fry your PSU, fry your other electronics, etc.
