Print your own 1:490 scale (estimated) model of the Northrop Grumman B-21 Raider aircraft! The B-21 Raider is designed with advanced stealth technology to make it virtually invisible to radar. Its shape, materials, and coatings minimize its radar cross-section. This flying-wing bomber uses clam-shell flaps for yaw control, which is pretty stinking cool!
There is a landing gear and no-landing gear version. There is also a version with a pitot probe as a flight-test version.
Suggested layer height: 0.2 mm
Suggested nozzle width: 0.4 mm
