Please use the 3MF file unless you want to mess around with the whole thing's scale. I have the scales tweeked to work so that parts fit together. Also, please ignore the non-manifold edge warning in Bambu Studio, everything prints.
I found an old photo of Mark Hamill wearing an early bit of Star Wars branding a few years ago. At that point they were calling it “The Star Wars”. I turned it into a t-shirt (not the one pictured) and then decided it would be fun to do as a lightbox.
This was my first attempt at a lightbox. What started out as something I hoped to take a few hours turned into way more and I'm still not totally happy with it. The conversion process from PNG, to SVG, to Blender file, and finally STL/3MF was messy. The nature of the original art means there was lots of little places where different colors showed up. I cleaned the whole thing fairly well but there are still a few issues.
I personally think it looks good both lit and unlit. There is a hole in the back for running wires, if you decide to.
Here is a link to the page which shows, and talks about, the early Star Wars branding:
