Adapter for SUNLU spools to fit A1 mini AMS lite

This adapter allows you to use SUNLU filament spools on the Bambu Lab A1 mini's AMS lite color changer. Otherwise these spools don't fit because their inner spool diameter is too large.

This is a somewhat unique design that is faster to print than some other common adapters. It relies on a little slot that the SUNLU spools have to lock the adapter in place. There is a corresponding peg on the adapter that fits in that slot. Note the spool hub is slightly tapered, and it's easier to insert the adapter peg-first from the side farthest from the slot. Just align the peg so that it will click into the slot. I included some pictures which should explain it better - it's simpler than I'm making it sound. :)

There's always a chance SUNLU will change their spool design, but I have also included the original Fusion 360 file in case you need to make modifications.

I hope you find this useful!
