hisl_0031: Model file names
For model file names: Use these characters: `a-z`, `A-Z`, `0-9`, and the underscore `(_)`. Use strings that are more than 2 and less than 64 characters. (Not including the dot and file extension). Do not: Start the name with a number. Use underscores at the beginning or end of a string. Use more than one consecutive underscore. Use underscores in file extensions. Use reserved identifiers.
