Ender-3 case cover for 60mm fan

thingiverse

I recently upgraded my Ender-3's power supply unit cooling system and scored a bonus 60mm fan in the process. Next, I turned my attention to optimizing the motherboard cooling setup for my printer using this new fan. My primary objective was to guarantee that air flow wasn't hindered by any obstacles, so I made sure the inlet area of the fan wasn't smaller than its impeller's surface area. To secure the protective cap to the cover, I opted for 2.5x10 screws with countersunk heads. This design feature allows me to easily remove the cover from the case without having to unscrew any screws – simply loosen it slightly and you're good to go!
