Search of an colour 3D-model for Printing

Hello everybody,

I’m from Germany an I’m
looking for an 3D Skyline model from a famous city (which city doesn’t matters). BUT which I can’t find
threw the Internet is an 3D model for colour 3D-printig. I have found
someone with a completly new technology in 3D-printing for print 3D models in
real colour from on .obj Database. Can you help me with this project? Or do you
seen or hear from anyone that such a model is possible to buy or can someone here build
such a colourful 3D printable model from a skyline?

Thank you & best regards from Germany
