Top off your row of houses with this twelve-piece variety pack of O scale ready to paint chimney pots, 3D printed in grey ABS-like resin and supplied unpainted.

The mix contains four different chimney pot styles, three of each, so you can avoid the slightly unsettling effect of a whole street with matching pots. Variety is what makes a row of terraces look like a real terrace and not a clone factory.

A clay-red base coat with a black wash brings out the texture, and a light dusting of weathering powder along the rims sells the look of decades of soot. For a Victorian terrace, mix the styles down a single roof line rather than along the street — that's how chimney pots tend to age in the real world, with replacements and repairs accumulating over time.

Turn a flat row of rooftops into a believable skyline with mixed-style chimney pots.
