It’s taken far longer than I wanted, but I am finally looking at a finished prototype for the Audrey Braille Display.

The goal now is to get this working smoothly, and thereby figure out what needs reworking. Hopefully, I can get to work on version 002 and have it ready later this month; in any case, as promised, here is the current design for this version, in Sketchup format:
Release under the Perl-Style Open Artistic License, the file contains the assembled model, with all parts as groups (and some collections of parts grouped as well, such as the motor mounts). This should make it easy to pull pieces out to see what they do, without damaging surfaces.
