Dear Sir/Madam, On the 27th of September 2021, I purchased the model of your Intertwined ring 3D model. We tried to print the STL file version of the Intertwined ring, but we were unable to print it because the ring in the STL file was in separate meshes. I wanted to ask if you can please send me the STL file version of the Intertwined ring 3D model with everything merged into one body and export it as a single closed mesh? Also, please make sure there are no stones. Thank you very much. Kind regards, Samuel
