Reusable spool for refill filament. The spool is fully compatible with original Bambu lab reusable spool. It can also be used as a replacement part if one half of your spool is damaged. The mechanism is identical to Bambulab. One part contains a notch for the paper core of the refill.

This is a full wall version. It can be modified to anything.

It can be printed from PLA but I personally prefer PETG.
