I liked the Rugged Box Design so I designed a Filament Swatch Card holder inlay for it.
the box can hold 26 Filament Swatches
uses 8 M3x30mm screws
this is based on someone else's design I just embedded a filament swatch holder into it.
the model's that my work is based on:

The author remixed this model.
