Do you have some rolls of filament laying around? Stacked on top to make space, but you always want one of the bottom spools...  This simple holder is designed to place your filament spools side by side, for simple overview and access. 

Size: 70mm width, designed for 200mm diameter filament spools (= all popular 1KG spools)

Just simple, practical and aesthetically 3D printed, not designed to be most minimal.
Hexagons just because they are the bestagons :) 

Note: No rollers = not designed for holding spools while printing, just storage.
