Filament guide for CR-10S, Ender-3, Alfawise U20, etc.

thingiverse

The lubricant on the Z rod can ruin your prints if the filament touches it. This guide helps prevent this behavior by running the filament directly inside the extruder. It prints easily in under 20 minutes and is compatible with many CR-10 style 3D printers, including the Creality Ender 3 and the Alfawise U20/10. Here on Thingiverse you can find other designs, but I dislike all of them. Some require screws, while others are too tight. The one I designed gives the filament some freedom, so it will never touch the Z rod. In the picture you can see this filament guide upgrade mounted on my Alfawise U20 and Creality Ender-3. UPDATE 29/01/2019 | A variant for 3D printers with a spool holder mounted on top of the frame has been added.
