Lake Taupō Wall Plaque

Why

Taupō has been in the news a bit in New Zealand recently as it has been having a few earth quakes.

Model Details

Data Source

The Taupō region topological data was sourced from https://www.opentopography.org/ using the Shuttle Radar Topography Mission (SRTM) Global dataset.

Note:  There appears to be a large island near the south eastern end of the lake, in reality this is not an island, but a swampy spit, the STRM topological data renders this as water. :(

Minimum layer height also plays a role as some features can simply not be rendered with 100% accuracy.

Tools Used

Paint.Net; Inkscape; QGIS Desktop, Fusion360, PrusaSlicer

Method

Relief data was selected and exported from OpenTopography.org and imported into QGIS Desktop. A full spectrum relief map was generated and exported as a png. This png was tweaked in Paint.Net and then converted to an stl using https://imagetostl.com/

The raw topographic stl mesh was then combined with other artwork (converted to SVG using InkScape) and sketches to create the plaque which was exported as a final mesh (the 3mf files inlcuded with this model) into PrusaSlicer which was then used to generate and tweak the 3mg project file and gcode.

For some reason I had real trouble making the wall mount void in the model itself, so I modelled it separately and then added it in Prusa Slicer as a negative volume.

Print with a colour change as the relief starts for maximum effect.
