I generated this model to be taken as a basis to create your own custom models, if you are a beginner it will save you a good time modeling, they are really light geometries that will give you great detail when printing them and it will be easy to modify.You will find 3 files in one this is the skull and the jaw together and the other two are separate pieces that will help you generate different postures or simply print the skull alone.
