Snap on Ender 3 Stock Filament guide bearing - fixed leaning

thingiverse

This design is virtually identical to theroar's non-all-in-one filament guide, with the addition of a bottom and side wall that prevent it from tilting. These walls keep the entire structure stable. The bearing itself is simply a copy of theroar's original design, without any modifications. Personally, I'm not a fan of all-in-one designs like this one. While they're an intriguing concept, the bearing doesn't always print well, often resulting in overhangs and unusual extrusion issues. However, printing the components separately has worked out well for me. Before assembling the guide, I applied a small amount of silicone grease to the inside of it. To avoid any mess, make sure to wipe off all excess grease from the bearing ridge and other areas where it may come into contact with your filament.
