Swatch Holder

With each new roll of filament I get I've gotten into the habit of printing a test swatch using the 3mmBox.stl file that can be found at: https://printrbot.zendesk.com/hc/en-us/article_attachments/202000470/3mmBox.stl
My daughter insists that we keep each swatch so we can tell what colors we have without opening our air tight filament storage box. As I've printed more and more swatches they were getting a bit unruly. So I designed this little holder to keep them neatly in place. It is one of my first attempts at designing something and my friend encouraged me to upload it. So here it is. Enjoy!
