When converting a 3D model, use a tool (like Blender, MeshLab, or online converters) that supports both your source format (e.g., OBJ, FBX) and target format (e.g., STL, glTF). Export the original model from its software, import it into the converter, select the output format, adjust basic settings (like scaling if needed), then export—this fixes compatibility for uses like 3D printing, gaming, or web display. For beginners, try free tools: Blender (full control) or online options like Convertio (quick conversions). Always preview the output to ensure the model’s geometry stays intact.
