Upper Filament Guide
thingiverse
I found the "Secure Filament Guide for Ender 3" by SlickStretch to be very useful, but the filament wore a groove into the guide and started to bind. So I bodged a guide roller from FragrantAbyss "Ender3 Filament Guide" onto the bracket. It's functional rather than aesthetically wonderful, but it works for me.
