Master Spool for BambuLab Refill

I don't know if you, like me, use a lot of BambuLab refill spools, but we quickly run out, especially when we regularly change filaments or colors. So, I imagined what I believe is the ideal Master Spool for BambuLab refill. The idea was to be able to easily and effortlessly swap refills from your spool, preventing the filament from untangling during removal. This Master Spool allows you to attach the refill with Velcro strips before even removing it from the spool, so you can re-store it without needing a spool. I've also integrated a filament guide to prevent unwinding during spool storage, as well as 3 types of support cylinders: One that allows you to add a 500g weight (or any other object to add weight) to prevent the spool from lifting in the AMS when there's little filament left (similar to my Universal Spool Weight available here). One that allows you to add desiccant bags to absorb moisture. One classic with just a hole compatible with external spool bracket and AM
