Elegoo Cardboard Adapter

This is a simple adapter to reduce the size of the center hole of Elegoo cardboard spools, so that it fits better on the A1 mini (and potentially others) support. The better fit prevents filament from getting stuck when the spool is nearing the end and weighs less, by not allowing forward movement of the whole spool which often results in it getting stuck or dragging against the printer. I tried several other models that try to accomplish the same thing, but none of them fit properly, This is a quick cheap print and solved my issue. You need to print two adapters, one for each side of the spool. Only tried with Elegoo PETG Rapid which is all I'm printing lately.
