Pegboard or stand alone parametric trays

This is my first real use of OpenSCAD. I needed some trays to hold various parts for the Fairfield County Makers Guild (http://makersguildfc.com) and could not find very much that met my need so I came up with this.
My requirements were that they be meant for counter tops or for use with pegboard. If you do not want for pegboards then comment out the module call to createPegs.
Editing the variables for L, W, and H you can make different size trays.
