Ender 3 Pro MeanWell PSU fan cover/muffler

thingiverse

This is my take on a fan cover/muffler for an Ender 3 Pro with the MeanWell PSU. Even though the PSU fan is actually an intake, I thought it would be fun to make it look like a car muffler. I whipped up the design in OpenSCAD in just a couple hours and have included the source so others can tinker with it. I was inspired to make this fan cover themed like a muffler after seeing [Ender 3 Fan Cover (Hot Rod Edition) | now with power supply mount](https://www.thingiverse.com/thing:3680099). To install, only remove one screw from the PSU fan, put the fan cover on at a slight angle, and re-install that same screw. Then remove the remaining screw, align the cover, and re-install the second screw. This should ensure that there is always a screw holding the fan in place and it won't fall into the power supply.
