After acquiring a Bambu Lab P1S with an AMS, I suddenly found my collection of tiny quarter kilo spools to be sad and useless.

I quickly discovered printable spools for refills, and then various respooling tools, but that felt like more effort than I wanted to give for all of these. Why can't I just have an adapter for all my existing tiny spools?
I took to Reddit, which led me to this neat little contraption:

which seemed promising

And while it worked as advertised, the spool itself was too narrow to fit over the AMS' feeder mechanism.

So back to the drawing board; I took two prints that I had already used successfully (see remix sources), and figured, why not both. So I just merged the two items together to have an appropriately sized and spaced spool gap, with a simple but reliable gripping mechanism.

which proved satisfactory.
