Ender 3 filament guide with bowden tube

thingiverse

I utilized the concept that bowder tube springs offer. It's a superior notion for filament guidance. What I disliked in the original design was that it couldn't be simply applied when something is positioned on top of the Z axis (bearing, knob). My version allows for easy installation. Another aspect I didn't appreciate - it's visually too weak. Although it never broke for me, it seemed amusingly fragile. Nevertheless, I decided to strengthen it.
