attached files in obj, fbx, mtl format
I also attached a rar file. with the compressed textures created in substance painter
vertexs:2282 edges:4536 faces:2256 tris:4512 UVs:2372
remember to change the color space in the nodes controller from sRGB to Raw in case you have any problem with the visualization of the textures
