<p>Originally published here: <a href="https://www.thingiverse.com/thing:3557650">Arrakis scaled one in sixty million by tato_713 - Thingiverse</a></p><p>This post is based on <a href="https://vignette.wikia.nocookie.net/warehouse-13-artifact-database/images/a/a1/Arrakis_map.png/revision/latest?cb=20160213221850">this official map of Arrakis</a> (suggested by the user <a href="/oshiricohn/about">Joy Cohn</a>), from the Frank Herbert's <i>Dune</i> saga. I created my own hand topographical map from this image, and then I used MATLAB R2016a to plot the topography in spherical coordinates, interpolating the missing areas in a similar way I have done with other astronomical objects. I added a "complete" version in which the missing areas were reconstructed based only on speculation. If you want to print the most cannon as possible, choose the normal models.</p><p>I made also a <a href="https://www.thingiverse.com/thing:4540505">"flat arrakis" or "board" version</a> using the entire topography.</p><p>The file's names explained: <i>name_1_x_10_y.stl</i> is 1 : x* 10^y. So _1_6_10_7 is 1:600000000 or one in 60 million.&nbsp;</p><h4>The size of Arrakis</h4><p>There are a good reference of the size and other characteristics of the planet since the big background of the Dune saga, provided by the book "Dune Encyclopedia". Arrakis, Dune, Rakis, is a planet about the size of <a href="https://www.thingiverse.com/thing:3557664">Venus</a>, with a composition similar of that of Solar System rocky planets. However the distances described on the books are far shorter than the represented on the map. It has two moons: Krelln and Arvon of 488 km and 201 km in diameter respectively. They are too small to make in the same scale as Arrakis.</p><h4>References</h4><ul><li><a href="https://www.mathworks.com/matlabcentral/fileexchange/4512-surf2stl">Surf to STL function for MATLAB</a></li><li><a href="https://vignette.wikia.nocookie.net/warehouse-13-artifact-database/images/a/a1/Arrakis_map.png/revision/latest?cb=20160213221850">Map of Arrakis</a></li></ul><h3>Other astronomical objects</h3><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49826">Inner Solar System</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49832">Artificial</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49820">Near Earth Asteroids</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49291">Main Belt Asteroids</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49829">Jovian System</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49828">Saturn System</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49830">Uranian System</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49345">Neptunian System</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49827">Centaurs</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49833">Comets</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49341">Trans Neptunian Objects</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49824">Extrasolar Objects</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49837">Sky Maps</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49831">Ancient</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49822">Speculative</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49821">Science Fiction</a></p>
