This is a manifold to line up a 100 strand fiber optic whip (specifically this one) with 4 SK6812 light modules (specifically these).

It was modeled using OpenSCAD and I've attached the original code so you can play with it. I had to increase the tube diameters to allow feeding the fiber strands through and it was easiest to split it up into 4 section of 25 and feed them in through the bottom holes.

I printed my final version upside down (cone point down) as it was easier to remove the supports that way.
