AMS Adapter for small Bambu Lab spool

This is an AMS adapter for the small Bambu Lab spool by Oscar Marcelo

I found the idea of spooling almost-empty filament onto a small, quickly printable spool, thus freeing up the actual spool for the refill pack, very appealing. Unfortunately, I only then noticed that the small spool does not work in the AMS (at least not when a filament change is pending and needs to be retracted).

There are many adapters for small spools here - unfortunately, they do not fit this one, because this spool is either too small, or too wide for the adapter.

Therefore, I designed these rings, they are simply pressed onto the outside of the spool. It is advisable to additionally use a spool weight or a dry box, since the spool with little filament is really very light and therefore the friction against the rollers of the AMS may not be sufficient.

Print the model in PETG or ASA if you plan to dry it with the filament.
