Where can I get an STL file?
Many CAD programs offer the option of saving your data as an STL file (.stl). There are also many options that influence the quality of the .stl file, such as the density value.This affects the number of triangles created. A further value is the angular tolerance, which changes the small details of your file. The smaller these changes are, the more triangles are generated in order to display your model. This guarantees a higher-quality model, but also creates a large size file.
