Modular spool adapter (Bambu Lab, Sunlu, Jayo)

Hello everyone! I made a modular spool adapter for the A1 mini stock spool holder. It just snaps together around the stock spool holder, no need to use glue to hold it together. The default diameter is used for official bambu spools, and you can slide on adapters to accomodate bigger spool diameters (so far the old sunlu spool, jayo spools and the new type of sunlu spools), and you can easily close it down with an endcap which uses a twist locking mechanism. This spool holder prevents the tilting of the spool and this way reduces friction of the spool and also prevents it from falling down during printing.
