Everything has changed.
I remade object 1 and reduced the size by removing unnecessary vertices that do not affect the details.
I changed the shape of the object to match the actual photo with the 3D model to make the position perfect. I also changed the thickness so that it is the same as the actual size.
I also paid attention to the UV direction and changed it so that everything faces in one direction.
I also made new materials and applied PBR materials.
