Customizable Drawer tool organizer

I liked the Plier / Wrench Organizer http://www.thingiverse.com/thing:1372608 but needed a different size for my tools so created a customizable version.

This is my first customizable object, please comment any issues you may find.
You can choose the general size of the container and the number of divisions.

UPDATE:

You have now control over the Lip size, putting 0 on any size means NO LIP.
You can now extend the prism of the lip, putting 0 on prismWith means NO PRISM.
