Ender 3 Filament Threader Guide for the Feeder, helps thread the filament into the feeder and reduce friction with the filament during feed and retraction. The friction was significant enough that a spool of PETG filament with ridges filed a vertical two mm long slot on the filament feed hole of my Ender 3 feeder black plastic block. It has a curved section where the filament threads in and a straight section where the filament threads out and enters the hole in the feeder black plastic block.
To install, you need to unscrew the 2 small screws that hold the Z rod block on the feeder, then slide the Filament Threader Guide in. Next make sure everything is line up before putting those two screws back and do not over tighten. These two small screws have lock washers so don't lose them.
After 3D print the Guide, the build-in scaffolds need to be removed by wire cutter and/or small metal files. I includes both STL files, with and without build-in scaffolds.
