Duramic to Bambu Spool Spacer

I designed this model to deal with the 3mm gap difference between the Duramic filament spools and the Bambu Labs plastic spool. Duramic PLA+ is a great filament that functions in the Bambu Lab high speed environment. It is readily available in an array of colors on Amazon only issue is that it comes on cardboard spools. But the inner cardboard spool fits over the Bambu Lab reusable spools with a 3mm of slop around it. This spacer fixes that problem and ensures a smoother AMS operation when loading and unloading.If you print my model add a make and review. If your feeling real generous boost my model.
