Modular Resizable Spool for Bambu Lab

When filament runs low, the original Bambu spool still takes up as much storage space as a full one.I designed this Modular Resizable Spool to solve that problem. The central hub locks together like the original reusable spool, but the sides are interchangeable.You can choose between several diameters (12cm, 14cm, 16cm, 18cm, and 20cm). This lets you shrink the spool without removing the filament, saving space and keeping your storage organised.With the smallest size, you can fit up to three partially-used spools in the same space as one full-size spool. And when you need to load it back into the AMS, just swap the sides back to the 20cm size for compatibility. To keep the filament secure, this spool uses an integrated clip built into the edge. It provides a simple way to hold the filament without needing separate accessories, although you can still use external clips if you prefer. IMPORTANTThe 20cm size is mainly intended so that a partially-used spool can be returned to the AMS if n
