Based on the Shield depicted in the MCU films, the Rogers iteration of the Captain America shield includes a detailed replica of the shield front and a composite replica of the shield back, including modeled straps, bolts and clasps. UVs have been cleaned up well enough to apply basic textures, but may require more cleanup, depending on needs. The model is provided in both OBJ and USD formats. Modeled at realistic scale (760mm*113mm), it is NOT a print model.
This is model designed for use in animation, not 3d print reproduction. Although, if not scaled down too much, high resolution printers may have some luck. It was modeled in a way that would allow it to be printed, if the model is not scaled down too small. But many details and parts are likely to be lost or would be far too fragile to survive the process.
