I think it would sell great. Commercial rights are available trough the crowdfunding link below. You pick a place, a date and a time, and it builds the sky exactly as it was above you: real star positions from the Bright Star Catalogue, down to magnitude 6, with the constellation lines and the planets that were up. You add your own text (a name, "the night we met", whatever), pick a plate shape (rounded, rectangle, circle or hexagon), and there's an optional desk stand. Everything prints without supports on any FDM printer. It's in beta right now, so for the moment you can only download the STL - and that's free, no account needed. 3MF downloads are for crowdfunding backers (see below). Would love to know what you think!
