Updated 3D Map Model Release Notes

3D Print Settings

Not all map styles may be available on MakerWorld due to MakerWorld’s low file size limits.
All styles are available on Printables.

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.

Map Variants Comparison

map variant comparison

Linear Scale: reflects the true elevation with a constant multiplier applied evenly across all the entire map to show sufficient detail.

Logarithmic Scale (incl: Square Root): exagerrates elevation differences in flat locations while smoothing out the pointyness of extreme elevations. Elevation detail is enhanced across the entire map at the cost of decreased accuracy.

Definition Meaning
REGION REGION Abbreviation
ESCALING Elevation scaling (e.g., Linear or Square Root (sqrt) or Log)
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.
POSTPROCESS (optional) Secondary style of a map VARIANT(e.g.,lowpoly)
PIECE##(optional) Interlocking pre-cut piece ## sized for 180 mm x 180 mm or 256mm x 256mm 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 on MakerWorld/Printables and comment with your request to get future additions and updates.

Projection (Alaska) NA Lambert Conformal Conic  
Projection (Hawaii) UTM zone 4N  
Horizontal Scale 1:2500000 (0.4mm:1000m) Effective resolution is 1000m x 1000m.
Horizontal Scale (Alaska) 1:2500000 (0.4mm:1000m) Effective resolution is 2000m x 2000m.
Vertical Scale (Linear) 1:500000 (0.1mm:50m) Vertical exaggeration is 5x. Elevations 0-40m are scaled between 0 and 0.8mm on a logarithmic scale for enhanced coastal detail.
Vertical Scale (Square Root) 1:500000 (0.1mm:50m) Vertical exaggeration ranges from 285-5x between sea level and ~4000m. Scaling is greater at lower elevation and lower at higher elevation, . Linear and Square Root elevation breakover at ~4000m.
Vertical Scale (Low Poly)   Vertical exaggeration is 3x of the base map vertical scale. E.g. Linear base map 5x * low poly 3x = final 15x.
3D Model Resolution 0.1mm  
3D Model Resolution (Low Poly) 0.1mm-2mm  
3D Model Resolution (Alaska) 0.2mm  
Highlights Streams, Lakes, Coastlines  
Maritime Boundary Submerged Lands Act Seaward boundary of coastal states generally 3 or 9 nm from the coastline. Maritime boundaries are included in the dual print models.
Model Base Thickness at Sea Level ~0.9mm Additional +0.9mm (dual) / +0.4mm (single) for locations not covered by water.
