This is a 3D print ready lips pendant. For the STL file, diamonds are not included. However, holes and prongs for diamonds are all ready. In total, there are 601 diamonds, mainly of 1mm size, with some smaller ones. The total time estimate to print the lips pendant is approximately 1 hours 56 minutes, as can be seen in the Ultimaker Cura preview screenshot. The model is designed with clean topology (quad faces). If you have any questions, please kindly get in touch with me. I'll be more than happy to assist you best I can. Thank you for your kind interest in my model. :)
