Brineward Sailing Collier 1850s Scale Model

A detailed 1850s sailing collier featuring a low black hull and twin square-rigged masts. Inspired by historic coal carriers, this model captures the authentic proportions of the era. Print with supports enabled to ensure clean details on the rudder and superstructure.
Size as supplied: 100.0 x 19.6 x 68.7 mm (L x W x H), about 1:320 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):
