1960s Ship-to-Shore Crane Scale Model

A faithful 1960s-era ship-to-shore container crane featuring a tall A-frame and long horizontal boom. The design includes separate trolley and hoist parts for dynamic display options. Print with supports enabled to ensure the overhanging boom remains stable.
Size as supplied: 100.0 x 57.5 x 66.1 mm (L x W x H), about 1:600 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 1:600 (real object about 60.0 m on its longest side).
- HO 1:87: scale uniformly to 690% (longest side 690 mm).
- OO 1:76.2: scale uniformly to 787% (longest side 787 mm).
- N 1:160: scale uniformly to 375% (longest side 375 mm).
- TT 1:120: scale uniformly to 500% (longest side 500 mm).
- O 1:48: scale uniformly to 1250% (longest side 1250 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.
