This is a filament intake I designed for my Anycuic i3 Mega (or how they call it now: the Anycubic M). Quite often it was quite fiddly to get the filament into the extruder correctly and I recognized, that the filament got worn off, when pulled over the metal part. This filament intake has a M6 thread and when screwed in, aligns the filament quite well with the extruder gear, so that it is much easier to put in the filament. Also the filament does not get worn off so much, because the intake consists of former filament and is not as hard as the metal part.

This intake will also work on other printers, as long as they have a M6 thread at the extruder.
