Toslink Fiber Optic Illuminator

Sometimes more important than brightness is just getting the light exactly where you need it and not blinding yourself by lighting up all of the surrounding area. All I had laying around was a toslink fiber optic audio cable and some flashlights, but the result worked surprisingly well.

This thing is just a simple adapter which allows me to plug a spare Toslink or S/PDIF cable into a Thrunite Ti flashlight I had. This adapter replaces the 12mm diameter lens and reflector from the flashlight, so it may fit other lights as well.

And here's the OnShape design file to modify it to fit other lights:
