I can’t buy a streak filter locally, but I’d like the anamorphic-style horizontal light streak effect on my DSLR. Is there a simple way to make one myself, and what materials or approach should I use?

The best ones use thin sheets of glass etched with regular parallel lines. It would be possible to replicate this approach using an old UV filter, a an etching tool and some sort of straight edge, but you can get the same effect by stretching several pieces of fishing line across a frame in front of the lens.

Yes. A streak filter can be improvised in front of your lens.
A common approach is a clear glass filter, such as an old UV filter, with regular parallel lines etched into it. In principle you could make one yourself using a straight edge and an etching tool, but the lines need to be evenly spaced and consistent to work well.
A simpler DIY method is to stretch several strands of fishing line across a frame placed in front of the lens. Keep the lines parallel and evenly spaced. The orientation of those lines determines the direction of the streaks, so horizontal lines will give one direction and vertical lines the other.
The effect is strongest with bright point light sources in the scene. As with any filter placed in front of the lens, expect some reduction in image quality or added flare, so test before important shoots.
