A friend asked me to do a quick model of a B-21 for them, and as all I could find on the internet was the same potato quality rendering of it, I think I did pretty well, even if I didn't bother to even give it engine intakes...
All pieces are a snug fit on my printer, if the p02 stand part doesn't agree with your model, I recommend varying it's height scale in your slicer to make it thicker or thinner.
