I made some changes to the openscad file. I was having problems getting the two side to join and be flush. I added CasewidthAdjusment variable so that the two side could be adjusted to give a little more room top to bottom for the powerpoles.

The image shown is of my first attempt. It is not the final project.

Notes:

Printing a brim around the two halves will help in keeping the flat sides from warping.
