I'm seeking black universal joints for a project. Do these exist in genuine LEGO form? I'm guessing the answer is no, despite hints (here and here). Ideally, I'd like the 3L size.

  • Do you know of a non-LEGO source that sells black u-joints?
  • Do you know if dying the standard gray LEGO u-joints black is possible, especially given that these parts are relatively small and complex?
  • Do you know if any rapid manufacturing process, e.g., 3D printing, could produce a nice u-joint?

    I'd also recommend searching for "build your own lego universal joint" - some of the solutions may be exactly what you're looking for.

    @RSchulz I don't see why you couldn't post your comments as an answer.

    Don't think painting UJ's is a good idea, the hinge points are rather small and paint likely would add friction there or glue the hinge points fixed...

    @RSchulz I don’t think a build-your-own would work for my project. I’m looking for the 3L u-joint specifically.

    @Alex I appreciate the note of confidence, but I was hoping someone would have something positive and more helpful to say. Mine is all speculation and doom and gloom. And I agree with (no at allowed) Michael Verschaeve that this part seems like the worst case scenario for painting.
