making sturdy optical fiber sculpture?


I’m sorry if this isnt the place to ask this.
I had the idea of making a figurine from optical fibers and control the colors with an Arduino.
Before getting into the technical part, what can I use to make the optical fibers sturdy? I’m thinking of putting them inside some kind of tube and/or covering them inside some kind of hardening translucent material. I’m sure someone can think of a better idea.
