Custom Piece – war flag of the Wehrmacht, the unified armed forces of Germany – 3D Print for LEGO Minifigure

This item is an accessory for a toy minifigure, consisting of a historical military flag mounted on a small black flagpole with a base.

As you correctly noted, the original design of the flag is obscured by a watermark. However, based on the Chinese filename, “德国国防军旗” (Déguó guófángjūn qí), which translates to “German Wehrmacht Flag,” this accessory represents the Reichskriegsflagge. This was the official war flag of the Wehrmacht, the unified armed forces of Germany, used from 1938 to 1945 during World War II.

This flag was flown by all branches of the German military (the Army, Navy, and Air Force) during the war. The full, unobscured design of this historical flag was:

• A red field.
• A black Scandinavian cross, bordered in white, that is slightly offset from the center.
• In the very center of the cross, a white circle containing a black swastika.
• In the upper corner (canton), a black Iron Cross (Eisernes Kreuz).

The flag piece itself is a small, printed plastic tile. This accessory is a key item for historical dioramas of World War II and is often used with German soldier minifigures.
