Filament Swatch Holder For Dry Box

I print off filament swatches for every new filament I get. I decided that the easiest way to label the filament in my dry box was to just use these swatches. The swatch slides in and out of the holder easily yet are secure enough that it doesn't fall out when moving. It is made for a 79.5mm x 30mm x 2mm swatch which is the default size for these swatches. Once printed, attach it to your dry box, printer, shelf, etc. using double-sided sticky tape or glue. Many thanks to Makkuro for the swatches! 

Edit:

9/1/22  Added a double holder version for two swatches. 

1/7/23 Added loose fit version of holders that don't hold the cards as tightly so they can be removed more easily
