Thanks Michael and BurrMan!

I considered modeling in another program and importing, but I just wanted to see if anyone had an approach. I've only been using MoI for about four months, so I'm still learning its capabilities. And I'm always impressed with the resourcefulness of the people in this forum!

BurrMan, thanks for the tutorial. I really appreciate the video - I'm not sure I would have been able to follow if you had written a text description, but your demonstration made it quite clear.

I appreciate the help!

I would suggest searching for something like "solidifying wireframe" or "wireframe thickening" and (also) having a look at the result's images.
