I've made several with mixed results. I've used wire nuts as inline spinner bodies. The strangest one that actually catches fish is a beer bottle cap. Poke two holes in opposite sides of the cap, attach split rings. Fold the cap in half with a couple of bbs in it. To the split rings attach a treble hook and turn buckle.

Ben, I have them. I have a lot of trouble with air bubbles. Haven't quite worked out how to avoid them. And the plastic is hot when you're trying to work with them so that makes it difficult. I've injected plastic until the mold is overflowing, but when it cools an air bubble forms. If anyone has worked this out, I'd love to hear how to avoid/fix it.
