Ender 3 filament guide
thingiverse
I was using borjang's filament guide until the pole delaminated from the base due to filament grinding during extrusion and retraction. Using the base with pole removed, I redesigned it to fit 2 x 608 bearings to straighten filament going into extruder. Parts list: 1 x filament guide base 2 x bushing 2 x M3 16mm + Nuts 2 x ID 8mm OD 22mm (608) bearings Update [09:05 PM 2018-08-13] You might find that filament tends to get in between left bearing and vertical plate. I added a pulley that can push fit into bearing. I also made slight adjustment to the position of bearings to reduce stress on filament. New parts: 1 x filament guide base 1 x pulley The bushing design does not change.
