So, I've noticed that my Ender V3 KE printer annoyingly squeaks, especially and mostly during wide and/or tall prints. Searching for a solution gave me nothing, so I had to examine it myself.
It turns out that at the sharp angles filament rubs against the metal part of recieving nozzle, making that noise.
So I've made this bracket guiding filament under the straight angle into the nozzle, snap it on and all squeaks are gone now. Retract wheel and lever are still easily accessible.
