Printbed Mini Adapter for Bambu Lab AMS

I like printing with lots of colors, but I don't always want to buy whole 1kg spools, so I designed a spool holder/adapter to fit Printbed's mini spools so that I can use them in my AMS. I designed a solid version and a hex version, which takes longer to print, but uses a little less filament. I've only tested the hex version, but they should work identically. I recommend printing at taller layer heights to save time, as it shouldn't affect any important features of the model.
