Round "U" Unreal logo plate from the Unreal Tournament 1999 era.
Backplate has a groove for inserting the circular piece if printed precisely enough, the āUā shape can be either glued on, or secured with small nails through four holes.
There are two variants of the symbol file, one in lower resolution (LQ), the other in very high (HQ).
The author marked this model as their own original creation.
