Filament Bearing Roller for top mount spools/Quick change
thingiverse
You'll need two 8x22x7 ball bearings, four M3x16 bolts, and four M3 t nuts to assemble this system. I engineered it specifically to minimize drag and pull on the filament when turning the spool during soft-filament printing: below 90A shore hardness. This design greatly boosts reliability and prevents TPU jamming in the extruder.
