Ender 3 V3 SE filament guide
This is just the bracket. Use the mount from the original.
I reinforced the part of the bracket that mates with the mount. I broke my first 2 prints because it broke while I was trying to drill out the hole. I think the tolerances are probably fine, but the tubing just didn't want to go through. I recommend using a 5/32" or an 11/64" bit (or both!).
I also recommend printing the mount diagonally, with the exit port face flush with the build plate. I used PETG.
Beautiful design.
