Cardboard Spool Friction Reducer for PRUSA MK4 / MK3 / MK3s Spool Holder low friction

Thanks. This works well 👍 Printed with PETG. (edited)

Fits perfectly on Prusa MK4 and MK4S spool holders. I kept getting STUCK FILAMENT DETECTED message but only with cardboard spools. Also noticed cardboard dust on the spool holders. This model fixed both problems.

Very nice and sturdy with PETG, Vase mode 0.3 layer height, 0.8 extrusion width. (edited)

I like them so much I printed 2 for each printer!
Printed 3 in IEMAI clear PETG and 1 in PolyMaker PolyLite PETG

On my Mk4 the version 2.0 is a bit to long, i use them in the original Prusa enclosure. The mounting is different, i Print some new ones, 90mm in my case.

Just what I needed to slightly reduce friction of paper rolls on original holder. Thank you. (edited)

Petg, printed some custom sizes for custom spool holder, works nice
