The chimneys were very high at the time to promote the natural draft of the boiler. Later they were shortened with the forced ventilation of the furnace by a fan (turbo fan), and the advent of heavy fuel oil heating which replaced coal.
The design is not yet finalized at the beginning.
The printing will be done in two sections because this chimney is 250 mm high, exceeding by a few centimeters the printing possibilities of my printer. The fitting of the two elements will not be seen.

Modifications made to fit the reality:
Modification of the initial angle from 5� to 3�:
