3D Curved hexagonal solid tessellation. SURFNETWORK
The Block just needs to be defined more accurately. But I'm not sure what should remain where it is and what should be adjusted to fix it. I drew LINEs [white] from its insertion point to the outer corners, on a full-tile Block Inserted at 0,0,0 and at zero rotation and scale factors of 1:
Zooming in, I expected the midpoint of that vertical Line to be at the insertion point, but it's not:
The midpoint of that Line is this far from the insertion point:
Delta X = 0.071884, Delta Y = 0.096132, Delta Z = 0.000108
And I expected the corner edges of the tile to run radially from the insertion point, i.e. to coincide with the endmost portions of my white Lines, but they don't:
And I looked at the midpoints of the top and bottom edges of the outer surface:
Upper: X = 0.099335 Y = 2387.362490 Z = -214.965189
Lower: X = -0.303606 Y = 2387.082958 Z = 218.047252
I expected the X values to both be zero, the Y values to be equal, and the Z values to be equal with opposite sign.
And the distances across the opposite corners on the outside face show that things don't line up right:
Lower left to upper right Distance = 499.804846, Angle in XY Plane = 359d55'58", Angle from XY Plane = 60d4'33"
Lower right to upper left Distance = 499.928004, Angle in XY Plane = 0d3'51", Angle from XY Plane = 300d1'22"
Side to side Distance = 499.797463, Angle in XY Plane = 0d0'10", Angle from XY Plane = 0d2'55"
The last distance is expected to be slightly different from the others, but those others should be the same, the angles in the XY plane should all be zero, etc.
I'm not sure what to suggest -- what (if anything) is in the right place, and what is the right size, to use as a basis for an accurate shape?
Yes, I got the wrong idea with my radiating from a single point. But even with the cylindrical arrangement, some of those values should still be equal, or zero, that were not quite.
So 15000mm circumference at tiles of 500mm means 30 tiles. Thinking about it....
One issue is that, while the top and bottom faces would be flat, to be really precise the sloped-face surfaces would be warped, because their top and bottom edges [yellow-circled above], since they radiate from the center axis at different angles, would not be parallel. Also, I think to be really precise the red-circled edges would be not straight lines and not even arcs, but helical.

You can get close to that by drawing Lines along the end edges of your cross-sections, and LOFTing between them, to get the white Surface here:
But while that gives you the warp, its long edges are straight. There's probably a way to draw a Helix of very small extent to define a path to Loft along.
EDIT: I got that to happen in the attached drawing, with a Helix of 1/120 of a turn, and height of 250. I just did the one edge, but maybe you can figure out the others.

Just open the file attached to my previous reply, pick the Helix which coincides with the inner edge of the Lofted Surface, and in the Properties palette:
you can change the Height. The Turn Height two slots below will change accordingly [that's what the total height would be if it went around one full turn]. Move the Line that coincides with the top edge of the Surface down to meet the new top of the Helix. The Surface follows when I do that, but if yours isn't set to maintain associativity, you would need to do the LOFT again.

I don't work in 3D enough to know how to do that, but Search this Forum -- the subject has come up before.
