FIT
- Sized for the AMS Iron Mountain Coal Car (1:20.3, 45 mm gauge).
- Load footprint 109 x 64 mm with straight sides.
- The load rests on the car's center brace, which sits 9 mm below the top of
  the car sides. The load's sides are 7 mm tall and no coal chunk rises past
  8.8 mm, so the coal stays just under the rim.
- Print 00_fit_test_ring_109x64.stl first. It is 3 mm tall and checks the
  footprint in your car before you print the full load.

BODY
- Solid with a flat bottom. At 7 mm tall there is no room for a light
  underneath, so it prints as one solid piece.

PRINT SETTINGS
- Flat side down on the bed, as exported. Import at 100% (millimetres).
- 0.20 mm layers, 3 walls, 15% infill.
- No supports needed.
- Black or charcoal filament for plain coal.
