A small test for a future project to see the colour change of the Aurora PLA by Faberdashery.
This ethereal pink shifts to a vivid blue under UV light as can be seen here by an in-bedded UV LED within a 20mm cube.
Unfortunately not great footage, but the general colour change can be seen within the short clip.
