I made this model to make samples from all the filament rolls i have, there were a few online to download, but a few were to big, others to small. so i made my own.

I also included a box and a top that can hold 100 cards, i made groups of 5 cards at a time so even if u have less swatch cards it still will hold nicely in the box.

The box and top i printed on 0.25 height and 15% infill. the swatchcards i printed at 100% 0.2 height
