Ender 3 PTFE Filament guide
thingiverse
This is a remix of another filament guide, It has been slightly modified to remove the cable clip to not interfere with Z-height and has been changed to math the shape the the Z-ROD slightly better, Uses 1 PTFE coupler and filament to softly guide the filament in, I've found about 1.5 - 2 inches of PTFE tube works best.
