Ender 3 Meanwell PSU cover

thingiverse

This cover was remixed from TAGinside's design. I removed the vent holes at the base, to force it to suck air from where the wires were, that way all the circuitry receives stronger airflow. I also widened the fan hole, so airflow is easier and the fan doesn't have to work as hard. other than that, I added some bevels to the edges and resized it so you don't have to. It works perfectly fine with the stock fan, but the 60x25 noctua will work too. In my testing with the stock fan, the cooling has been MUCH better. Infact, the power supply stays very cool now and the fan even turns off, signifying that the PSU is indeed staying cool. Previously with the metal plate covering the PSU comes with, it never turned off/stayed on constantly, and it was uncomfortable to even touch. This cover isn't a silent covering though, it is still "loud", so a different silent fan would definitely work better. One more note: The Meanwell PSU's fan seems to blow down, into the PSU, towards the circuitry and out where the wire connections are made/the bottom. I flipped the fan so it sucks through the bottom instead and blows out the hole as it seems to have better airflow that way.
