Introduction

The PRUSA filament spools are just one millimetre too tight to properly fit the AMS Lite rollers. You can use them on it, but you need to push the roller with quite a lot of force and then the rollers get semi-stuck in the spool…

This is ancient history with this PRUSA-compatible spool adapter!
This design is print-in-place, snaps into place like the original rollers using the same mechanism and provides a smooth enough rolling of the spool (I tested it only in PETG wich seems to be “slippery” enough, still haven't tried in PLA).

Remix details

I just enlarged the outer diameter to slightly over 52 mm to fit the Prusa spools. Let me know if you need another size!
