This is a minimalist light box/filament light transmission and gradient test. It consists of the main body, the back, plates that are meant to be printed in the color of your choosing that are divided into 5 stepped thicknesses from 0.2 to 1.0 mm thickness, and an 0.6 mm diffuser plate that can be printed in white or color. The idea is to use this light box to test color blending, and plate thicknesses, showing all the different color combinations you can achieve through the use of different filaments. Color plates must be printed in 0.2 layer heights.
