5 ft. Block Wall (Jointed) 90 deg. Intersection Sections; 2-Long Right Side Sections with 1-Column; HO Scale (1/87), each section approx. 2.11"L x 0.13"W x 0.70"H; arrives unpainted with a white, versatile plastic finish.
Use an Exacto Knife to cut away the joining strips. The joining strips are used to make the walls an integral model during printing, which keeps the printing cost much lower. Each wall column has a vertical groove to accept the tongue of a wall section to make a 90 deg wall intersection. Spray paint all of the walls with a plastic bonding paint of your choice. I have good luck with Rust-O-Leum 2X.
