No Painting or Weathering Needed. Our Ready To Run (RTR) range of HO scale models are 3D printed using special materials such as “iron infused” PLA filament that creates a Real Rust finish on the model, or our cradles and other items 3D printed using “wood fiber” infused filament to give a wood textured finish. Browse our ever-growing RTR range here.
