Spool Adapter for Polymaker/Overture to Bambu

What this part does:When placing Polymaker & Overture spools into the Bambu Lab spools, the hub diameters are not similar. So the filament hub will freespin inside the spool.

This part takes up the extra space to create a proper fit and more importantly, it adds back the tab which locks rotation in the original Bambu Lab refill design.
