M1337 spool drum adapter

something goes bump in the night “Honey, get me the filament box!” If you have a M1337 you need to feed it. If you're here, you probably have some empty spools laying around. Here's a way to help both of those problems. I haven't tested it yet but the spool spins freely enough in the box it just might work without bearings. This fits 2pc bambu spools and gives you a starting point to wind up the fodder and releases cleanly and easily at the end.
