Filament Roll Sleeve for Prusa Spool Holder

I created this Filament Roll Sleeve that slips over a Prusa spool holder to allow smooth rotation of the filament spool when using spools that snag or that provide high resistance when turning on the spool holder. See the photos for examples of some of the spool "features" that can cause uneven spool tension for the extruder.

06 NOV 2023 - Added more photos, and added a STEP (.STP) file so you can adjust it to whatever type / size of filament spool holder that you use!

There are fancier designs out there - with PTFE tubes and bearings, but this simple design does exactly what I need it to do.

The provided STL file is intended to be printed in Nylon (or PETG) and does not require supports.

PrusaSlicer 3MF files are provided for generic Nylon (preferred) and for generic PETG. G-code files are provided for the Original Prusa MK4.

The Filament Roll Sleeve seen in the photos was printed in generic White Nylon with a 0.4mm nozzle at 0.3mm layer height with a 15% gyroid infill.
