Mechanical Reefer Freight Wagon 1950s

This model features a white steel box design with an integrated fuel tank and cooling unit mounted under one end. It is inspired by the ADR-015 6.1 mechanical reefer wagons used in 1950s freight transport. For best results, ensure your slicer settings account for the required supports on the undercarriage components.
Size as supplied: 100.0 x 31.2 x 37.9 mm (L x W x H), about 1:175 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 1:175 (real object about 17.5 m on its longest side).
- HO 1:87: scale uniformly to 201% (longest side 201 mm).
- OO 1:76.2: scale uniformly to 230% (longest side 230 mm).
- N 1:160: scale uniformly to 109% (longest side 109 mm).
- TT 1:120: scale uniformly to 146% (longest side 146 mm).
- O 1:48: scale uniformly to 365% (longest side 365 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.
