Yet another extruder idler arm (623 bearing)
thingiverse
Revamped idler arm in jag's extruder filament guide to accommodate a 623 leftover bearing from twotimes' lowrider build. Adjusted its end by filing off some material to avoid rubbing on the extruder motor shaft bearing. However, the model design should be modified to provide sufficient space.
