Filament guide
thingiverse
This is a replacement filament guide that you can install in the top rail of your Ender 3 or Ender 3 Pro. It includes only the handpiece and clip. You will need to print the ring and two spacers from this Thingiverse model: https://www.thingiverse.com/thing:3052488, which I highly recommend using as a bottom filament guide. First, install an M4 bolt into the 608 bearing and attach it to the handle.
