The third, and hopefully last, iteration of the spider is coming along very nicely. This time it is printed with the carbon fibre reinforced filament.
It looks like the thickness of the vanes will be no more than 1.5mm - better than my earlier estimate of 2mm. If rigidity turns out to be a problem, I will be able to add extra layers of carbon tape and still not exceed 2mm.
The second attached picture shows the milling of a 16mm wide and 0.25mm deep channel in one of the vanes, needed for the FFC ribbon cable.
The milling took two minutes, but the precision fixture required two hours.
