Skimwell Hovercraft Scale Model 1960s

A 1960s passenger hovercraft featuring a flat raft hull, enclosed cabin, and dual rear ducted propellers. Inspired by real-world Skimwell designs, this model captures the era's utilitarian aesthetic with clean, unlettered paintwork. Print with supports enabled to ensure stability for the raised superstructure and rear air units.
Size as supplied: 100.0 x 69.7 x 50.4 mm (L x W x H), about 1:400 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 1:400 (real object about 40.0 m on its longest side).
- HO 1:87: scale uniformly to 460% (longest side 460 mm).
- OO 1:76.2: scale uniformly to 525% (longest side 525 mm).
- N 1:160: scale uniformly to 250% (longest side 250 mm).
