Tighter fitting segmented flex tube

thingiverse

I took Beaton's tube design and tweaked it by increasing the diameter of the female side by about 1mm using Meshmixer. When I printed it at 0.2 on my MK3, it fit perfectly snugly, a far cry from the original which was quite loose for me. As an experiment, I also tried printing this design at double its size with zero infill and it mostly worked out, but one of the "fingers" cracked slightly. If I end up using the larger size, I might give three shells or some infill a try.
