The chain was made specifically to be printed and casted so all aspects like shrinkage, stone settings, etc.. have been taken into account when designing.
The chain can be preset with round stones of 1.3mm.
It was printed and casted in our lab successfully as can be seen in one of the pictures.I've included STL files for a single link, the 3 parts of the clasp, and a full chain of ~16 cm.
If you want any changes, don't hesitate to drop me a message.
