It is not really obvious how to distribute the Capillary mass - they are arranged in a somewhat ad hoc manner, with more of the excess length being
absorbed at the D9 end.
Therefore I propose that they should be modelled as:
4 wedges with the same phi as the Disc Cooling Pipes

Cooling Pipes and Foils extend from midpoint between Discs 2 and 3 to far (Disc 9) end of SCT.
They follow the 3-stacks of Tapes (of which there are 4 per quadrant).
Their extent in phi is about 9.5 cm.
They have a fairly uniform density in z.

Geometry
Phi Fibres run in between pairs of LMTs, ie at 18 and 72 degrees in phi in each quadrants - they fill the gap between the LMTS, ie a few cm wide.
Like the LMTs, they build up in z, so:
z (1st model) Locate groups of fibres for each individual Disc between Disc and end of Cylinder.
or
z (2nd model) Locate total mass of groups of fibres as a triangular wedge between two ends of Cylinder.
