/**
    Screwed these to my front wall.
    
    There is a similar script Words/Outline.foocad without the screw holes.
    If I were to rewrite this, use Outline.foocad to create the numbers.
    This implementation existed before ExtrusionBuilder could handle hollow shapes,
    so it creates the outlines "manually".
