After building a TD-1 from AJAX3D i needed a storage for my filament samples. I i tried to design one.

The samples have a total length of 10,5mm and a usable length of 8,5mm which is enough to be used with the TD-1 TD measurmant tool from AJAX3D (see pictures)

You can print signs numbered or blank, to identify your samples or writing down the TD value.
