Ender 3 filament guide with bowden tube

I used the idea that bowder tube springs. It is the best idea for filament guide.

What I didn't like in the original design, that you can't just put it on if you have something on the top of the Z axis (bearing, knob). So my version you can put on easily.

Another thing I didn't like - its to weak visually. Funny but never broke for me. Anyway I desided to make it stronger.
