The ADGZ was an armoured car built in the 1930's by the Austro-Daimler company for the Austrian army. After the country was taken over by Germany, it was included in the German arsenal. It saw action in WWII right from the beginning, being used in the fight for Danzig in 1939.
Wikipedia has more information about the original.

The 4 guns are too thin to 3D-print. Buyers should add them with lengths of wire - see the picture.
