Hexagon Filament swatch with magnet

A Hexagon shaped Filament, i use these on the outside of my filament storage containers.

Houses a 5x2mm (or 6x2mm) Magnet on the back of the hexagon.

the one i use has a small indent for a sticker on the front, so i can add the details of the filament on it.

size of the sticker is 19x38mm
