4 piece interlocking prints at 100% scale are in separate print profiles due to MakerWorld file size limits. For additional map styles, see Printables listing.

California, USA (CA) Topographic Relief Map with Rivers and Coastal Waters

California, USA mountains, coastlines, streams, and lakes in a dual or single color topographic and hydrographic map! All topographic states in the USA of Plastic project are at 1:2500000 scale and interlock with each other similar to a puzzle.

Show off streams, lakes, and coastlines with filament that is glow-in-the-dark or translucent — or simply use a different color from the base!

*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.

The models are in 3MF format which is like STL but better. 3MF has smaller file size and can store separate land and water objects that are aligned for easy dual color prints. 3MF is supported in Cura, PrusaSlicer, and other 3D slicers.

Recommended print settings

Print the model flat. You can do a manual color change mid print to get interesting color transitions at higher elevations. Printers without multi-material capability should print the *-single.3mf models.

Download the optimized Cura print settings profile for topo maps HERE.

You can scale the model up or down as needed to fit your printer size, the final map's scale will just be scaled accordingly. E.g. 200% scale on a previous scale of 0.4mm:1000m results in 0.4mm:500m

If you rotate or scale models to fit your printer in Cura, merging objects (Ctrl+Alt+G) beforehand will help keep the dual color print objects aligned.

Printing this will test your 3D printer's XY precision, Z-axis stability, retraction, cooling, and oozing!
