Hi metric tensor, do the triangles follow a specific algorithm for how they're supposed to be arranged? Like at a certain angle or something like that?

For making the long vertical cylinders, I'd probably draw a larger circle in the middle, then a smaller circle off to the side and use Transform > Array > Circular to copy it, then extrude those up.

For the triangles if you can get points placed where the triangles are supposed to go, you could then draw lines between them, and when you have a big set of lines you can draw a circle down on the xy plane away from them, then select the circle and use Construct > Sweep and select all the lines as the rail curves and that will make tubes around all the lines.

It looks like a repeating pattern so you can probably make one layer of the triangle tubes and then replicate it using Transform > Array > Dir.
