Updated 3D Map Model Release Notes
Unless otherwise specified for specific maps, I have designed the models for a 0.4 mm nozzle diameter and 0.1mm layer height. Recommended print settings are any multiples of these specs.

| Definition | Meaning |
|---|---|
REGION |
REGION Abbreviation |
ESCALING |
Linear or Square Root (sqrt) elevation scaling. |
EXTRUDER |
Dual or Single color (extrusion) model |
STYLE* (optional) |
Model special style or subregion. STYLE is only present when the model file is a special style or the model is exclusive to a special subregion. |
REVISION |
Revision number. See release notes for the latest improvements. |
PIECE##† (optional) |
Interlocking pre-cut piece ## sized for 180 mm x 180 mm bed. |
*Default STYLE is water features model located over submerged low lying lands. This submerged land may be visible when water layers are printed with a transparent filament. Default style minimizes usage of secondary (water) filament color. transparent style has water model features that extend all the way through the land for maximum light transmission when used with glow and transparent filaments.
†If multi-part files are not present, I have not created interlocking models for this state yet. Follow me and comment with your request to get future additions and updates.

China
China model is at same scale as USA except for the following. Streams and base thickness are 4x thicker so that model can be more easily printed at 25% scale.
