About this 3D model

I found that even with the filament coming from the tower, the filament would tend to walk to the side of the extruder and jam. This piece clips around the delrin bearing and leaves a centered slot for the filament to pass through. Printed on the Simple with standard settings. This thing was made with Tinkercad.
