Hearthsea Steam Coaster: 1890s Scale Model

A detailed 1890s steam coaster featuring a single funnel, derrick masts, and well decks. Inspired by real-world coastal vessels, this model captures the era's industrial aesthetic with clean, unlettered paintwork. Print at 100mm length for optimal detail, ensuring supports are enabled for the masts and superstructure.
Size as supplied: 100.0 x 23.3 x 60.9 mm (L x W x H), about 1:700 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 1:700 (real object about 70.0 m on its longest side).
- HO 1:87: scale uniformly to 805% (longest side 805 mm).
- OO 1:76.2: scale uniformly to 919% (longest side 919 mm).
- N 1:160: scale uniformly to 438% (longest side 438 mm).
- TT 1:120: scale uniformly to 583% (longest side 583 mm).
- O 1:48: scale uniformly to 1458% (longest side 1458 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.
