Start from the structure
Extruded tubing divides less by material than by cross-sectional structure. Once the channel count and layer count are set, the usable materials and reachable dimensions narrow with them.

The length ceiling moves with the dimensions. Multi-lumen runs to 3000 mm, but the reachable length drops as the outer diameter shrinks. Tell us the cut length and packing unit you need and we will reply with what is achievable.
