Puffling Steam Launch 1850s Scale Model

A faithful 1850s scale model of a small open steam launch featuring a slim wooden hull, tall funnel, and canvas awning. Inspired by historic short-crossing vessels, this design captures the era's functional elegance with clean, unlettered paintwork. Print with supports enabled to ensure the delicate superstructure and propeller remain intact during removal.
Size as supplied: 100.0 x 31.5 x 61.2 mm (L x W x H), about 1:200 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 1:200 (real object about 20.0 m on its longest side).
- HO 1:87: scale uniformly to 230% (longest side 230 mm).
- OO 1:76.2: scale uniformly to 262% (longest side 262 mm).
- N 1:160: scale uniformly to 125% (longest side 125 mm).
- TT 1:120: scale uniformly to 167% (longest side 167 mm).
- O 1:48: scale uniformly to 417% (longest side 417 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.
