1kg MasterSpool to Bambu Spool Adapter

DasFilament just came out with a new spool size of 1kg, and therefore a new masterspool with new measurements. To make the refills still fit the reusable Bambu spools, I created this adapter.

It comes with three different ways to attach the filament end to the spool:

• Deep: put the end of the filament inside the adapter, try to make it at least half the way
• Side: fold the filament around the edge and secure it in the recess with the Bambu spool
• Hole: similar to Bambu cardboard spool hearts, just stick the very end of the filament in the small hole and secure it with a tight angle

Only time will tell which one is the best (or if a completely new design is needed) - so please give me feedback on how well the end held on to the spool, especially after being half emptied and used in an AMS / MMU. (The photos are of the “deep” version, the other ones are still in use) 

I measured the adapter to the current Bambu spool sizes (mine are from 2024 and newer), but I've seen other older measurements mentioned, which might not fit.

Print it with default settings or draft settings, and a little support
