The building exterior has been printed using an HPEnvy 6540 printer and look very good up close. Condition is New. The building graphics are printed on self adhesive paper. There is 1-3D printed section on the front making this a semi  flat structure which is painted red. The flat building's are printed on 8  x 11  inch full sheet shipping labels and attached to cardboard which give These flat structures a more realistic looking lustre. The difficult part of this structure is already completed when you buy this structure in that it is pre assembled. The 3D printed parts are glued in place. The flat building in this set measures  9 inches wide, .25 inches deep, and 10 inches tall at its highest point. The flat structure is larger in width than any of the other buildings I’m selling on my site. Still, It is extremely light weight and can go anywhere on your O scale train layout. Why pay an arm and a leg when you can have realistic looking buildings at a fraction of the cost of what some other plastic, metal or wood structures would cost? With 3D printing I am now able to make buildings with far more more intricate designs.  Shipped by USPS Parcel Select or UPS.  Seller chooses shipping. I do combine cost of shipping with multiple orders from my catalogue.
