Comments.Text: They don't show up as black in any inventory, but that doesn't rule their existence out. But they do seem unlikely to be available by the usual not-in-set means (test bricks, Pick-a-Brick wall, etc.). As far as coloring, I'd think it'd be a lot easier to dye (or paint) something light to be black instead of the other way around.

  (Asked by: username_0 on 2022-04-19)
  
  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](https://www.bricklink.com/catalogPG.asp?P=9244c01&colorID=11) and [here](https://www.brickowl.com/catalog/lego-black-universal-joint-4)). 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](https://www.brothers-brick.com/2013/06/30/50-shades-of-bley-iain-heaths-mad-lego-science/) 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?
