(Prior discussions here and here.)

1. I believe part 72706 should have 10 ribs rather than 9, as every photo I can find of the real part does.

2. Dimensions: I took some screen measurements from photos like this one, which support a rib-to-rib pitch of 2.5mm or 6.25 LDU, matching current practice. That also supports an overall length of 25mm, which is closer to the nominal 3L size of the part (especially with the natural squishiness of a real hose). It also also supports the 2L/6-rib hose being less than 16mm, as discussed in the second thread above.

3. I think the rib subpart should be a little fatter and rounder. In particular, the width of the rib should be greater than that of the gap; my measurements give an approximate ratio of 7:3. I plan to re-work this subpart for my own use; is it worth doing so officially? This would also affect the flexible segments k01 and k02.
