Generic Trilobite, new design!

NOTE: I have uploaded an updated file; the one you want is TribGeneric-B.3mf. The one thing I've always … not disliked, but been disappointed in, with my trilobites is the wide space between thoracic segments that was necessitated by the mechanism I was using to make them articulated. Just wasn't right. Then one day when working on something else, I got the idea that maybe a ball-and-socket joint would be better? So after three days of designing, printing, re-designing, tweaking, printing, tweaking and lots of caffeine, I came up, at last, with this guy! I still can't make it roll up into a ball (but I have ideas), but there is a full range of motion to every segment! This isn't any particular type of trilobite. Any suggestions?
