I wanted a filament guide that has a nice long sweeping bend and fits Bowden tube in since that stuff is pretty slippery I guess. Also, I needed a place to mount my BigTreeTech Smart Filament Sensor V2.0.

I wanted it to be pretty rigid so I used 3 mounting points, all the default screws should work you won't need to replace them.

So you'd want some PTFE tube and a BTT SFS V2.0 in order to use this on your Ender 3, CR-20 or whatever family of printers has this same Z-axis setup.

At the highest Z-axis point it looks like there should still be clearance but I'm not likely to test that anytime soon.

If i remember I'll come back here sometime and give an update to how this thing has treated me.

Feel free to modify the design and post it or whatever, I don't really need attribution but if you want to give it that's up to you.
