scale broken concrete debris for dioramas and rail layouts. This pack includes a compact heap plus separable slab fragments, short cylindrical pieces and small chips sized for viewing distances. Use the grouped heap as a fixed vignette next to a demolished foundation or scatter the loose chips along sidewalks, curbs and service entrances for believable urban decay. Placement tips: orient slabs with the largest flat face down for the cleanest print and glue larger pieces to bases for durability. Finishing: apply a thin primer, follow with a dark wash into fracture lines, then lightly drybrush edges to simulate exposed aggregate. Note: prototype dimensions were not supplied with the legacy source — confirm fit in your slicer before batch printing.
