Utah topographic map with major streams and lakes highlighted.

The individual 3D printable 3MF files are cut for your convenience and fit together once printed. The files are in 3MF format instead of STL in order to store separate base and river objects that are aligned and ready to print. 3MF is supported in Cura and PrusaSlicer.

Print with dual extrusion or single extrusion with Z-hop method on the rivers object.
