This is based on the Bambu Lab reusable spool, but designed to be printed on the A1 mini. This design also reduces the time and quantity of material needed to print.

I have tested this with the AMS Lite, and it should work with the regular spool holder. Could possibly be used for the AMS, but I don't have it or a compatible printer, plus, why would you waste time printing this when you can print a full size one anyways.

Also just a quick reminder not to take apart the spool with filament remaining as it will make a mess and tangle it 😂
