SUNLU Spool Reducer Clips

Loose SUNLU spools on your low-friction holder? These snap-fit reducer clips fix that. These clip-on reducer inserts are designed for the rollers used in the Low Friction Spool Holder for A1 / A1 Mini model. They solve a simple problem: some SUNLU spools have a larger inner hole, so they fit too loosely on the original rollers. This adapter reduces the effective roller diameter difference and helps the spool sit more firmly and with better alignment. The inserts are made as 2 snap-fit halves that mount directly between the roller end flanges, so there is no need to disassemble the holder. Once installed, they create a larger contact diameter for the spool while the roller still spins freely on its bearings. Main purpose: - for SUNLU spools with larger center hole - compatible with the rollers from the Low Friction Spool Holder for A1 / A1 Mini - improves spool stability on the roller - simple press-fit / snap-fit installation - no screws, no glue How it works: - each reducer is made of
