Earth Sea Relief Globe
by pmoews, published
Here is a traditional earth relief globe. It displays the sea surface, unlike thing:86681, Earth Relief Globe, which shows the sea bed. A small 3.5 inch globe, it is meant to be quickly and easily printed.
It was created with the program "globe" by DJ Moews, available under the GNU GENERAL PUBLIC LICENSE. Globe can be downloaded from http://djm.cc/dmoews.html.
The input file used with globe was gmted2010. Gmted2010 was created by DJ Moews from the USGS GMTED2010 data set and is available at http://djm.cc/dmoews.html. See the README associated with the data file for details.
Input to globe was: --map altitude data/gmted2010 5400 2700 sbigendiandibyte --gridpoints 256 --map-scale 120 >earth_sea_relief.stl. Earth_sea_relief.stl was centered and scaled by 0.0000075 to yield a globe about 3.5 inches in diameter.
Two stl files are available:
earth_sea_relief_plus_base.stl - the same globe with a base added at the south pole
The openSCAD program used to add the base is relief_plus_base.scad.
On my Replicator I used two shells and 2% infill and printed earth_sea_relief_plus_base.stl directly on the build platform. Print time was a little over 4 hours.
Earth_sea_relief.stl was printed with a raft and external support and took a little under 6 hours to print.
