This work is a remix from the wonderfull work of Extrutim

With this swatch, that is meant to be printed in .16 layer height or lower, you have an area to write the name of the filament tested, and an area that will be ironed, this way you can in a single card see how the color looks ironed and not ironed.

Just use the .3mf and change the settings you see fit including the text, do not forget to print in a small layer height so that the ironing occurs in the supposed space.

You can go to the original model of this remix to print a beautifull case for the swatches.
