This is a model of the RQ-4B, from Northrop Grumman. These aircraft are absolutely huge and impressive - To say nothing of the political implications.
This model is set up to print on a 200mm x 200mm build plate, which pops out a print about 11" wide. Feel free to rotate and scale to your needs.
When printed in the original orientation, the infill lines up with the fuselage, and looks kinda like ribbing. Neat!
