I have design Flying Wing in Solidworks and make it for 3d printingI have uploaded Step, Stl and Source Files ( Solidworks supported Version 2017-2019)

A flying wing is a tailless fixed-wing aircraft that has no definite fuselage. The crew, payload, fuel, and equipment are typically housed inside the main wing structure, although a flying wing may have various small protuberances such as pods, nacelles, blisters, booms, or vertical stabilizers

Disclamier :The Model isn't tested by 3D printing, though its made for 3D printing. So you might need to add/remove to make model work worthy.
