PTFE Adapter for Self-centering Spool Roller

PTFE Guide for Self-Centering Spool Roller (3kg–5kg Spools)This adds a PTFE filament guide to the original self-centering spool roller design, making it easier to maintain smooth filament feeding for heavy spools. Designed in Fusion 360, the guide ensures reduced friction and better alignment, especially for high-weight spools that can cause drag or uneven feeding. I just glued it in with CA glue and it has been working great.FeaturesIntegrated PTFE guide M10-0.75 for ultra-low friction filament movement.Compatible with the original spool roller design (link above).Maintains the self-centering functionality while improving filament handling.Easy to print and install—no additional hardware required beyond the original model.Glue in place with CA glue or glue of choice.Why Use This?Heavy spools often create tension and uneven filament paths. By adding a PTFE guide, this minimizes resistance and helps prevent filament snags, ensuring consistent extrusion for long prints.Print SettingsMate
