Rolling filament guide.

thingiverse

I crafted this design after an extensive search for a reliable filament guide, similar to the one found at https://www.thingiverse.com/thing:2917932. The existing option has a major flaw - it slowly wears away the ring component, ultimately causing the filament to become stuck. To address this issue, I created a new version specifically for use with a 609 bearing and a standard screw from my old Anet A8. You have two options: a longer version of 18cm or a shorter one. I highly recommend choosing the larger design (MAIN BODY.STL) only if you have sufficient space available. Remember to print two copies of the inner bearing.stl file.
