I've looked over this model's normals to ensure they were all aligned correctly, and I'm absolutely certain there are no problem areas. Looked over every polygon just to make sure. However, the validation service still tells me there are inverted/mixed/irregular normals. You may view the model below, as well as the attached .stl. Could someone please assist me? I really want to get this necklace made and see what kind of results I get. I'm really unaware of what the issue could be.
