Ender-3 Filament Guide

I've done just two simple modification. I've cutted part of the holder to put it in place without unmounting half the printer and I've added a bit of space for the brass screw nut. I've added this little space for the screw on the 3D model after I had to use a cutter to enlarge the hole when I was mounting this piece. Please, write me if you would try to print this model and you have an issue.

[EDIT] I've noticed that the thin plastic that hold the filament in the inlet is wearing out. I've uploaded a second version with a bit thicker.
