Hey, So I have MASTERCORE refills from UK Filament and I didn't like the system for reusable spools as it didn't work well in the AMS being cardboard. I wanted to be able to use the BambuLab Reusable Spools with the UK Filament refills but found they didn't fit.

My solution was to make an adapter designed to fit the Bambulab Reusable Spool.

It worked a treat so I'm sharing it with you all so you may do the same!

I would recommend printing in Tough PLA but should work with anything really.

To use it, just slot the notch end on the side of the reusable spool that has the bump, then add the MASTERCORE refill and then carefully take the cable ties off without unravelling the spool. Add the other side of the bambu spool and close.

Top Tip: Its a snug fit so what helped me close it was placing the whole thing on the floor and using both hands apply pressure and twist.

Boom! You now have an AMS usable spool refill :))
