Zuid-Limburg relief map

thingiverse

My friend, a geography teacher, retired this year and is fond of Zuid-Limburg's landscape, the only non-flat area in The Netherlands. I decided to create a 3D print of this region for him. Searching Thingiverse, I discovered OmNomNom Creator, a program that creates surface maps from grayscale images, but I needed a contour map of Zuid-Limburg. Eventually, I found a Dutch Waterschappen website providing customizable height data maps. After creating a grayscale map and processing it in Photoshop, I used OmNomNom Creator to generate an OpenScad file. It took 15 minutes to compile and render the file, saving as an STL file which was over 26 MB. The print came out great, and my friend loved it!
