1850s Brick Waterworks & Reservoir Scale Model

This detailed 1850s waterworks features a brick pumping station, tall chimney, and reservoir in a single cohesive structure. Inspired by historical industrial architecture, it captures the era's engineering with clean, unlettered surfaces. Print with supports enabled to ensure stability for the tall chimney and overhanging elements.
Size as supplied: 100.0 x 90.5 x 75.5 mm (L x W x H), about 1:320 scale.
Print settings: PLA, 0.12-0.16 mm layers, 0.4 mm nozzle (0.2-0.25 mm for extra-fine detail), 3 walls, 15% infill, 3-5 mm brim.
Supports: needed for undersides and overhangs. Use tree/organic supports touching the build plate only; enable 'support on build plate only' to keep detail faces clean. Support Z distance 0.2 mm and interface layers make removal easy.
Pre-oriented: the 3MF is already placed upright on the build plate (z = 0) - print it as supplied, no rotation needed.

Rescale table (always scale uniformly):
- As supplied: about 1:320 (real object about 32.0 m on its longest side).
- HO 1:87: scale uniformly to 368% (longest side 368 mm).
- OO 1:76.2: scale uniformly to 420% (longest side 420 mm).
- N 1:160: scale uniformly to 200% (longest side 200 mm).
- TT 1:120: scale uniformly to 267% (longest side 267 mm).
- O 1:48: scale uniformly to 667% (longest side 667 mm).

Included files: the 3MF model, a print guide PDF (settings, supports, bed placement, colours, painting, reference views), a dimensions and scaling sheet, orientation and support tips, a real-world inspiration note and a README.
