Ring Filament Guide _ Ender Series

The 3D model is a simple ring with a groove running along its outer edge. The groove is designed to either allow the filament to pass smoothly through it or enable the ring to roll along with the filament as it feeds from the dryer to the printer. This design minimizes friction and prevents the filament from scoring or marking the filament holder. The ring is lightweight, prints quickly, and can be made from PLA, though I chose PETG for added durability. This small but effective component improves filament management and prolongs the lifespan of the holder.
