A nice borrowed enclosure for the Arduino, and a *very* rough beginning of an enclosure for the display.  All done and shared in TinkerCAD(.com).  The Arduino enclosure I'm considering (below) is borrowed from the MK II project shared here, but I want to ensure it will be moisture-resistant.

UPDATE: OK, a little more work, and a little more acceptable, but still far from "finished".  Gotta get more familiar with TinkerCAD.
