I might be repeating myself here, but: Why do you use rings for Daisy rather than n-sided “polygons” with straight edges. Ie straight rods connected by ferrules? One would think that should keep the shape better, as a ring is already bent and thus will be prone to further bending with force, while a straight rod will not bend as easily when subjected to force (until it buckles). The aim seems to be to keep the tethers from compressing radially, thus my question about star vs ring structure of the spacers (is there a better name for these parts? I am using “spacer” as they ensure space between tethers). So we actually have at least three spacer options:
- ring
- polygon
- star
And then I might suggest a “lattice” arrangement (just the idea, the shape itself is just improvised and unoptimized)
My point being with all this, that the weight of each spacer limits the maximum altitude of the rig and should be optimized quite a lot imho.
