We are working on a Map to STL converter for a while now and this is one of the first models created during beta which was also printed.
The above print was made on a self-built work-in-progress Reprap Prusa Mendel, so please don't mind the low quality.
The model shows the terrain around 47.7303361, 12.881588.
I will put a website with a map based converter creating such STLs online within the next few days. Just some last testing necessary...
