This papercraft is the Insignia of the Brotherhood of Steel, a quasi-religious technological organization operating across the ruins of post-war North America, with its roots stemming from the American military and the government-sponsored scientific community from before the Great War, from the Fallout video game series, the paper model is created by [unknown].
In the Brotherhood symbol, the gears represent their engineering knowledge, the sword is their will to defend themselves, the wings represent the uplifting hope that the acquisition of lost technology represents for mankind's salvation following the devastation of the Great War, and the circle represents the fraternal unity that makes the organization a true brotherhood.
Another interpretation is that the Brotherhood's symbol represents each of the organizations different orders. The sword represents the Paladins, the wings represent the Elders, the large gear represents the Knights, and the two smaller gears represent the Scribes and the Initiates, whose services keep the Knights supplied with the information and the manpower required to get their jobs done. This interpretation could also be supported by looking at the Outcast's insignia, which is absent of wings & shows that they do not need Elders or their equivalents.
While both the original Brotherhood of Steel in the Core Region and the Capital Wasteland faction of the Brotherhood use different colors for different elements of the symbol, the Midwestern Brotherhood uses several mono color variations. A blue version is used by the Midwestern Brotherhood's Knights and Paladins, a black one by the Scribes and an orange one by the Elders. The golden/yellow variant seems to symbolize the Midwestern Brotherhood as a whole. The Midwestern version of the Brotherhood symbol is also reversed horizontally - the large gear is to the right of the smaller ones, not to the left as in the original. [Source: wikia]
