It is a test of odd number of segments, and how to design the cut for the floppy twist.
5-segmented is printed in PETG, 7-segmented in ABS and acetone vaporized. It is a material test to me. I've found, PETG is much better than ABS and PLA. only it cannot be acetone vaporized. PETG has less warping, is much more stable. it sticks to printbed very good (I use kapton tape). It can be printed with my ABS nozzle (no cleaning). Needs 10C more temperature (ABS=240C, PETG=250C). If price is ok, then buy PETG fi
