looks like i'm not the only one with the same idea!
"Laser" cutters are becoming more and more affordable (or in your case access to a "laser") so I'd expect a few people on the scene tbh mate.
Anyway nice tower, nice etchwork, though not enough of a playable area, so probably more of a scenic piece. Maybe something more wargame playable for the next outing of the Deathstar?
You may etch when ready!
