Did some cleanup of the files and organization, pushed a project repository on GitHub.  This repository includes some more photos (I think I've maxed out the gallery space on Hackaday.io), the OpenSCAD files, and a 2D CAD drawing ( DWG, DXF, and PDF) of the panel.  The panels form the basic building blocks of the design.

Yet to do, documentation-wise:

• complete and upload the final assembly drawing
• notes and comments on the design
• explanation of some of the OpenSCAD craziness

As for the enclosure, the remaining six rails of the correct length will arrive today. I will start assembling everything tonight.  I should have it assembled and running by the weekend, knock on wood.
