Customizable Wire Access Grommet

I've decided to go back and turn some of my first 3D printable designed into parametric models. This is an updated and customizable version of my thing "Wire access grommit" from way back in August of 2011.

You can scale both the grommet and openings size in millimeters using sliders in customizer. Text can also be added to the lid of the grommet.
