Voltage-Controlled Acoustic Drone Instrument - Rough Internals Render

Here's a (rough) render of the internal workings of the Voltage-Controlled Acoustic Drone Instrument I have dreamed up. (Maybe V-CAD works as a name? VolCAD?) Blue parts represent 3D printed parts, orange is used to denote the wheel and the coupler for the threaded rod, though I see no reason that these could not be 3D printed as well. The black part is a NEMA 17 stepper and the white rod is, naturally, a 6mm threaded rod. The purple-ish transparent sheet represents the soundboard. What do you suppose are the chances that I could use a sheet of acrylic as a soundboard?

It's not what I would call a final product by a very long shot: tuning pegs are not represented in this render, nor is the ball bearing for the rod, nor are the strings, and as you can see, there is no mechanism in place to change the pitch of the chanter strings--yet. Furthermore, there's nothing holding the whole stupid thing together; it would all readily fall apart with the combination of its own weight and the tension of the strings.

That said, it's enough to work with to test the concept. Feel free to drop a comment, suggestions, encouragement, or just to tell me this idea is totally freaking crazy and I should probably just stop.
