An attemp to create something useful (rather than decorative objects and toys) with UV color-changing filament. The design is meant to be partially printed with regular plastic that matches the “shade color" of the color-changing material. So when exposed to UV light, the symbol will become more visible.

As a result of my experiments, the difference in colors could be clearer. However, at the time the pictures were taken, the UV index was only between 3 and 5, which may not have been sufficient. Additionally, I was able to achieve a darker green color using a UV flashlight.
