Ender 3 Power Supply Passive Cover

prusaprinters

<p>Passive cooling upgrade for the non-pro Ender 3's power supply. I have made it a year back, and have been using it since, without overheting, in an open enviroment witohout much draft. I did many 12+ hour prints without any problems, shutdowns, signs of burns or anything. I tried existing “silencers” for the power supply, but none were this efficient. I have also added a small heatsink to the top of the unit to help with heat dissipation.</p><p>It is a drop in replacement, you can use the stock screws.</p><p><strong>Use at your own risk, I take no responsibility if your house burns down because of this.</strong></p>
