Filament guide for Snapmaker - Additionnal part

My first filament guide (https://www.thingiverse.com/thing:2778493) worked like a charm until I found one filament broken just at the feeder level. This part (to be fasten at the rear of the X axis as shown in the first picture) prevent any unecessary bending on the filament while extruding.

For information, I used M4x8 screws bought on Amazon: https://www.amazon.fr/gp/product/B015A37GLW/.
