The image shows three objects on a gray surface. On the left side, there is a small rectangular metal plate with a small hole in the center. Next to it, there are two small pieces of metal, one of which appears to be a small piece of wood or a similar material. The metal plate has a textured surface with a pattern of small circles and lines. The wood is dark brown in color and has a rough texture. The objects are arranged in a triangular formation, with the largest piece on the left and the two smaller pieces on the right.
