Feeder bearing mod for flexible filament
Small upgrade to the alternative feeder by IRobertI https://www.youmagine.com/designs/alternative-um2-feeder-version-two
Prevents flexible from slipping of the bearing.
Big thanks to IRobertI for the alternative feeder.
Order the smaller 13mm bearing from RS. Print the ring and bore spacer and press on to the new bearing. Printed from ColourFabb XT at 0.1mm layer height. It may need a file hear and there but works great.
Note: Designed to be used with IRobertI's v6 feeder.
