Dear customer,
This model has been made especially for further production, hence the package contains a print-ready model of a ring only. No any materials are included.An OBJ format with a lowpoly mesh may be of help in making any changes to the model if needed.
Please, while printing, do not forget to take into account the shortage of the metal after the casting. If necessary, please rescale the model on 1-5% to avoid shortages during casting or making molds.In case you need this model in other formats (3DS MAX for instance) or you might need to do some changes to the model, please, do not hesitate to make a request, I will be glad to be of help.
Yours faithfully, Svetlana
