Steam Locomotive Kettle Scale Model

This detailed model captures the classic silhouette of a vintage steam kettle locomotive. It is inspired by the iconic rolling stock from the early industrial era. Print with supports enabled to ensure clean details on the wheels and boiler.
Size as supplied: 100.0 x 23.9 x 28.9 mm (L x W x H), about 1:90 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 1:90 (real object about 9.0 m on its longest side).
- HO 1:87: scale uniformly to 103% (longest side 103 mm).
- OO 1:76.2: scale uniformly to 118% (longest side 118 mm).
- N 1:160: scale uniformly to 56% (longest side 56 mm).
- TT 1:120: scale uniformly to 75% (longest side 75 mm).
- O 1:48: scale uniformly to 188% (longest side 188 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.
