rigid or torsion .. size .. angle.. all is customizable

when done ... the chain has separate parts easy to group and move rotate duplicate etc ...

edit point allow to change the shape of each curve ... copy paste for more complex group of chains

and if you want more personnalized chain ... create a shape ... Array along curve does the job
