A stackable mini-filament model display rack to show and organize every of your filament! 

It's stackable so you can expand as needed. Use only 1g of every spool and turn your filament into your collection.

Please use 50% of Henlor's Bambu Lab Filament Display Spiral Ball Model. 

Also, cards can be hidden behind every spiral ball to record its type and brand.
