An interview on the benefits of 3D printing for accessibility, discussing 3D printed tactile learning models." Something along the lines would work for me.

As far as more information goes, I would add "This video discusses how 3D printed tactile models can be used to provide students with a better understanding of concepts or ideas that are usually presented in graphical form. Concepts such as the shape of a DNA or what a neuron looks like can be difficult to understand if you cannot see the graphs. With 3D printing, we can print these models out, with braille markers and QR codes, to give students a more hands on understanding, and giving them another way to study for their classes.
