The stove is printed in several parts: the base (printed upside-down), the stove itself, chimney pipes and a small curved section of pipe to connect to the wall behind it. The chimney sections slot into each other, but will need a dab of superglue to hold them in place. The stove also needs to be glued onto its base, with the straight side of the base facing front.

The model in the photograph shows a chimney consisting of two pipe sections, but obviously, a longer chimney can be made using more sections.

I printed all the parts (including two chimney sections) at the same time on my Makerbot Replicator+ using its default settings.
