Ender 3 Power Supply 92mm Fan Case

thingiverse

This is a remix of OderWats WellFan Mean Well PSU Mod that's adapted for the standard Ender 3 PSU. Changes were made to fit the mounting holes and accommodate a larger, 92mm fan. I used a SUNON 92mm fan that's 24V and can be swapped easily without needing a buck converter. If adjustments need to be done, you can comment on this thing and I'll do my best to help ASAP. 02.08.2020: A more visually pleasing honeycomb pattern was added for the fan and intake. Elements were aligned and a chamfer was added for the fan screws to fit better. The version pictured is the older design with two M3 screws+nuts, but it had issues with the upper two being hard to get in, so they're missing from this picture. The current design has larger 5mm holes that should allow you to use standard fan screws that thread into the fan itself. Two pairs of posts inside the bottom part can house LM2596 buck converters, but clearance needs to be checked first; proceed with caution if you try to make use of these mounts.
