This model has real world scale and measures 4 cm in depth, 101 cm in height and 102 cm in length. The railing unit can be copied and further lined up as shown in the second preview image.
All used textures and maps are included: one texture / diffuse map, one normal map, one metallic map and one glossy map (invert for roughness). Each image measures 4096 x 4096 px. UVs are unwrapped and everything is named logically.
Should you need the model for 3D-printing, please contact me, so I can prepare the mesh for it.
Do not hesitate to ask any questions.
