This is a piggy bank (German: Spardose) as a simplified model of the Kölner Dom.
The filament used in the pictures is PLA Rauchquartz by Unicofil (http://www.unicofil.de/de/pla-rauchquarz.html)., Due to its partial transparency it looks better with thicker walls than in the provided STL - adapt and regenerate from OpenSCAD if interested.

Notes:
Supports are really only required for the coin slot, the roof and towers should be printable without supports (my support angle is set to 60).
