Ender 3 Hotend Fan Cover
thingiverse
I designed a cover for the hotend cooling fan because sometimes I notice tiny strings and particles of filament getting sucked in by the air stream and ending up around the fan blades, causing annoying noise. The solution was to create a cover that is placed in front of the fan with a hole facing upwards, which potentially reduces the chance of stuff from the hotend getting inside the fan. This cover attaches to the metal fan mount via magnets, making it easily removable for maintenance. EDIT: Additional versions were added 5mm x 5mm cube magnets are now available 5mm x 5mm cylindrical magnets have been included
