Ender 3 Fan Cover

thingiverse

I really appreciated @mtlcan's fan cover design. Unfortunately, after printing it out, I discovered not only were the arm sides asymmetrical but also the underside of the fan cover was flat and far from aerodynamic - or symmetrical for that matter. To fix this issue, I streamlined both side arms to ensure everything was even and added "Up Down" arrows instead of a logo, while also providing a blank version. (The blank one isn't shown here.) Additionally, I removed the overhang as it seemed unnecessary and would make vertical printing much easier. The file labeled "U D" is the updated design you see now. The "Empty" file, on the other hand, has no lettering or logo at all. When printing this part, please orient it vertically so that the Part covering the fan is positioned above the arm sides where the screws attach, allowing it to stand up straight.
