Shark Fin pick
After some gathering with friends who good at music, I know there is a ocean of knowledge behide a simple Guitar Pick.
Difference sound was produced if you use Pick of different kind of thickness. And each shape have its own special usage.
I start to think, why not using 3d printer to make one?
That is how I started this.
