This uncommon wedding design of the rings is unique, it was made by me in about 2012 and has not been sold massively. The rings can be characterized as minimalistic and solid, its golden version is pretty heavy and looks luxurious.
This model has been made especially for further production, hence the package contains the STL file for printing and no any materials are included.
An FBX, MAX and OBJ formats 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.
Please, do not hesitate to make a request, I will be glad to be of help.
