Ender 3 Filament Guide Modified

thingiverse

I appreciated the sleek, uncomplicated design of the original filament guide by Ian_Crossley but it started sagging after some time. I've got my filament spool bracket mounted vertically on top of the machine using the two bolts that secure the top of the printer together. Occasionally, if the spool was carelessly wound and putting more strain on the filament guide than usual, it would warp at the mounting screws on either side of the z-axis rod and rise up. I felt this was undermining the purpose of the filament guide plus it screeched loudly anyway. Eventually it remained permanently warped upwards so I modified the design in Tinkercad to add a component that extends under the extruder bracket and prevents it from rising.
