I printed this for my O-gauge layout. Reduced in size by 25%. It comes out with pretty thin walls but I had Slic3r watch out for thin perimeters/shells/walls. I set the layers to 0.1mm and it printed pretty well on my Original Prusa MK2s. Printed in black PLA, Bottom spray painted a grayish color.
Set top/bottom layers to 4/3. Set Extra Perimeters if Needed, Ensure Vertical Shell Thickness and Detect Thin Walls.
