Open the STL files in your slicer using millimeters and 100% scale. Center each part and place it on the bed. Keep the building’s base flat, roof undersides down, and smokestack upright with its socket down.
The building needs about 226 × 158 mm of bed space, plus room for a brim. If you resize it, scale every part by the same percentage and check the small details in your slicer.
2. Use a stable setup
The original setup used PLA, a 0.4 mm nozzle, 0.16 mm layers, 3 walls, and 12% gyroid infill. Supports were off. Adapt these starting points to your own printer and material.
Use a 6 mm brim for the building and 3 mm for the roofs. For the tall smokestack, use a wide 12 mm brim and slower speeds to help it stay steady.
3. Assemble gently
Let the pieces cool, then remove brims and loose strings. Match the four roof shapes to their building sections and align the underside sockets with the locating pegs.
Fit the smokestack onto its footing peg beside the boiler room. Dry-fit everything first; lightly clean tight sockets rather than forcing them. The roofs can remain removable.
