Travelling Mail Van Scale Model

This 3D-printable scale model features a classic mail van with a letter slot, side net arm, and few windows. Inspired by real-world freight wagons used for transporting mail cargo, it captures the vintage charm of railway logistics. Print with supports enabled to ensure the intricate details of the side net arm and windows remain crisp.
Size as supplied: 100.0 x 51.3 x 58.3 mm (L x W x H), about 1:98 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 1:98 (real object about 9.8 m on its longest side).
- HO 1:87: scale uniformly to 113% (longest side 113 mm).
- OO 1:76.2: scale uniformly to 129% (longest side 129 mm).
- N 1:160: scale uniformly to 61% (longest side 61 mm).
- TT 1:120: scale uniformly to 82% (longest side 82 mm).
- O 1:48: scale uniformly to 204% (longest side 204 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.
