Wanhao i3 filament guide
thingiverse
Simple spool holder that uses any skate bearing to provide zero drag on the filament. Requires a single skate bearing with an 8mm ID, along with an 8mm or longer M3 bolt. Print two washers and position them between the bearing. Insert the 3D printed bolt through the washers and bearing, then press it firmly against the filament guide main part. Secure the filament bolt in place by screwing in the M3 bolt through the main part. Next, slide on the filament guide pulley, and you're ready to go. I recommend printing the Filament Guide Pulley with supports standing upright, not on its side. Enjoy!
