Based on Olympus VN-711PC digital voice recorder, but I didn't place the Olympus trademark on this model to avoid copyright problems. Also I've made this model some more 'metallic', than the original voice recorder. The model is low-poly (296 verts), not triangulated.
PBR: base color, metallic map, AO map, normal map and roughness map are included.
PrincipledBSDF shader is used, it's available in Blender 2.79 and higher.
