Hot end cover; Ender 3
thingiverse
I designed this to seal off the hot end fan on the standard Ender 3 setup. It also shuts off the nozzle cooling fan. This is useful when printing with PETG. Simply back out the two screws, slide it in place, and tighten them down. You're good to go. This also blocks the nozzle cooling fan! Don't use this if you plan on using the cage fan.
