Looking for Flexible/adjustable caps and fiber optic cables for laser

Greetings ALL

I have a 4mw laser pen that I would like to put a cap on so I can direct the laser light
In the direction I choose. Is there something like this out there? I know they have the flexlights

but these have the light at the end I would like to have the light at the backend and have the laser light
travel down the fiber optic line. See animation below link of what I’m trying to find/build
