Polymaker 3kg Cardboard Spool Adapter

A remix of the official Polymaker Cardboard Spool Adapter which fits their 3kg cardboard spools.

Step file, .STL, and CAD (Alibre) project are available in the downloads tab.

I recommend printing it out of something with a higher HDT than PLA so it can be dried in a filament dryer. You will also need a printer capable of printing a 250mm diameter object.
