Freight Yard Loading Dock Ramp Scale Model

This model features a realistic loading dock ramp with detailed structural supports and a smooth incline. It is inspired by the heavy-duty ramps found in busy industrial freight yards. For best results, use supports for the underside of the ramp to ensure a clean print.
Size as supplied: 100.0 x 29.5 x 23.9 mm (L x W x H), about 1:200 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 1:200 (real object about 20.0 m on its longest side).
- HO 1:87: scale uniformly to 230% (longest side 230 mm).
- OO 1:76.2: scale uniformly to 262% (longest side 262 mm).
- N 1:160: scale uniformly to 125% (longest side 125 mm).
- TT 1:120: scale uniformly to 167% (longest side 167 mm).
- O 1:48: scale uniformly to 417% (longest side 417 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.

Images: all pictures are digital renders of the 3D model, not photos of a printed copy.
Note: the upright orientation of this piece is still being double-checked - preview it in your slicer and rotate if needed before printing.
