A simple detachable swatch fan, each set holds 9 swatches with top and bottom cover or 10 swatches without the covers. You'll need a M3 x 12mm screw for binding screw post assembly.

The stencil font used in this design is a free one from Behance. Download the font to create your own using the included blank swatch.

I used the box version (doesn't have the notch) as a label on the cardboard box.

AMS tip: You can print four different materials/color swatches at once using Others/Special Mode/Print sequence by object.
