Recently I was looking for a simple way to play audiobooks for a family member who is not used to touchscreens. As it turns out there are not many available options that are simple enough to use. As I have never worked with audio players or speaker, this seemed like a useful and straight-forward project.
Making it easy to use does not mean that a device has to look ugly. I tried to build something that looks like a finished product with inspirations from 1980s electronics and Teenage Engineering.

I love this design, would you be able to release the source files for the STL's? I'd like to adapt them for a 3.5" screen I have on hand.
