U Bend Filament Guide
thingiverse
I didn't want to build a shelf for my Filament Heater so I decided to run the filament through the top. Since this is a Direct Drive Mod. The inside track is pretty smooth, especially if you print this in a finer layer height, but there was a recommendation made to me that I should put a PTFE tube through the holes, and it worked wonders. I even made a second version of the foot, the piece that slides over the top of the frame, specifically for the #ender 3 SR1 since it is special and then I zip-tied the filament runout censor along the path of the filament, it works great.
