I wanted to make some text boxes for checking the different shades of colors at different layer heights but also something that I could hang on the wall or sit on my desk as a decorative piece. This is what I came up with and it serves my 2 functions well.

The layer heights of the test chip goes from 0.2 to 1.6.

Measurements for Usb C Connection on the main box is 14mmx6mm.

Thanks to RevHazlett for the tips and inspiration who's original test box this is derived from.
