Locomotive Dewcell: 2060s Hydrogen Freight Model

A sleek near-future freight locomotive featuring rounded cabs and roof-length hydrogen tank pods. Inspired by the Dewcell design, this slim, tall machine showcases clean panelled sides on two separate bogies. Print with supports enabled to ensure the smooth body surfaces and wheelsets detail correctly.
Size as supplied: 100.0 x 18.9 x 30.5 mm (L x W x H), about 1:220 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 1:220 (real object about 22.0 m on its longest side).
- HO 1:87: scale uniformly to 253% (longest side 253 mm).
- OO 1:76.2: scale uniformly to 289% (longest side 289 mm).
- N 1:160: scale uniformly to 138% (longest side 138 mm).
- TT 1:120: scale uniformly to 183% (longest side 183 mm).
- O 1:48: scale uniformly to 458% (longest side 458 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.
