Prusament is generally good stuff, but because of Prusament's horrible half-measure in trying to do cardboard spools they have really bad dimensional width variance in their assembly. This means while some Prusament spools fit nicely in the AMS, many do not.
As far as I can tell, this is down to the flexibility of the cardboard spacer in the middle and how hard someone at Prusa pushes on the sides when assembling the spools. This variance makes for a maddening experience where some spools fit the Bambu AMS, and some do not. I wish they wouldn't make them like this.. but since they do… we need a solution.
To fix this, and to allow the polycarbonate prusament spool sides to be reused, I went looking for solutions, but I didn't quite love what I found. I took the best solution I could find and remixed it here to make it stronger and more compact, to ensure no AMS loading issues.
Changes from parent:
Printed in Bambu PC and Prusament ASA for heat resistance to allow me to put these in a food dehydrator to dry the filament on the spool. If you use these filaments like me, make sure not to forget to use shrink compensation. I use 99.5% in orcaslicer for bambu PC.
Printed at 0.16 layer height.
License set to match the parent rather than my normally more permissive license.
