PolyTerra AMS Spool Adapter

IMPORTANT! This cardboard spool adapter ONLY fits the PolyTerra line of PolyMaker cardboard filament spool. If you have a different PolyMaker line of filament, like PolyLite, PolyMax, PolySonic, PolyMide, PolyWood, or others, please use my other spool adapter here: PolyMaker AMS Spool Adapter. I designed this Spool Adapter for the Bambu Lab AMS for my PolyTerra cardboard spools, since none of the other adapters currently available fit it properly. This design utilizes the holes of the carboard spools to help lock the adapter in place as well as an anti-slip lip at the top (prints without supports) that will prevent the adapter from coming loose inside the AMS. I exported this as a high quality STL and as a result the curves on the outside have no flat edges and will spin easily inside the AMS. The model only uses 8g of filament. Orientation of the holes does NOT matter for this model. You may use both the top and bottom sets of holes.
