FIT
- Sized for a G scale mining cart with an inside opening of 3 5/8 x 4 1/2 in
  (92.1 x 114.3 mm) and sides 1 1/4 in (31.75 mm) deep.
- Load footprint 91.3 x 113.5 mm: 0.4 mm clearance on each side.
- The load tapers 3 mm per side toward the cart floor (85.3 x 107.5 mm at the bottom).
- Print 00_fit_test_ring.stl first. It is 6 mm tall and checks the bottom
  footprint in your cart before you spend filament on a full load.
- Open bottom, no legs or ribs inside. The cavity is 82.6 x 104.8 mm, room for
  an LED board, LED puck or battery tea light. Use LEDs only: PLA softens
  around 60 C.

WALLS
- Sidewalls about 0.9 mm, roof about 1.0 mm under the coal, so more light gets
  through translucent or glow-in-the-dark filament.
- A 1.35 mm rim runs around the base for the first 3 mm for handling.

PRINT SETTINGS (0.4 mm nozzle)
- Rim side down on the bed, as exported. Import at 100% (millimetres).
- 0.20 mm layers, 2 walls, 5 top and 5 bottom shell layers, 0% infill.
- 5 mm brim.
- Removable supports under the domed roof. Pull them out through the open
  bottom before the light goes in.
- Use your filament maker's glow settings. Print one load first and check the
  light, layer bonding and handling before printing the set.
