Not long ago, certain persons to whom I am married introduced me to the idea of book nook inserts, basically little dioramas scaled for bookshelves. While they take up valuable space on what are surely crowded shelves, they are quite nifty. So I thought I'd give it a shot.
I had a number of ideas, but the first one was something Death Star-like. Naturally, it was 3d printing to the rescue. The parts are mostly from a Death Star diorama set and and a bunch of Death Star surface tiles from this guy. Print, prime a uniform gray, add on a few accents here and there, finish with a thin, dark wash, and glue to the inside of an improvised box. I added some LED lights (mostly shining through custom drilled holes) and a landing platform for a TIE fighter.
For a first attempt, I think it went tolerably well. It's wider than I'd like (wasn't really sure how it would come out, but I can use this as a gauge for how much narrower to make it), but it does give the impression of Death Star-ness. And I have ideas for more...
