3D Printable Boxcar Freight Wagon Scale Model

This detailed boxcar model captures the classic design of traditional freight wagons used for general cargo transport. Inspired by real-world rail logistics, it features accurate proportions and panel lines for a realistic look. Print with supports enabled to ensure crisp details on the roof and undercarriage.
Size as supplied: 100.0 x 32.8 x 38.9 mm (L x W x H), about 1:150 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 1:150 (real object about 15.0 m on its longest side).
- HO 1:87: scale uniformly to 172% (longest side 172 mm).
- OO 1:76.2: scale uniformly to 197% (longest side 197 mm).
- N 1:160: scale uniformly to 94% (longest side 94 mm).
- TT 1:120: scale uniformly to 125% (longest side 125 mm).
- O 1:48: scale uniformly to 312% (longest side 312 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.
