Eckhouse 3D model for 3D printing

Another 3D model made specifically for a 3D printing project for the same customer as previous. This building is from 1910 Berlin, "Eckhaus". It will be 3D printed by the customer and used in their massive model train diorama depicting the area along the railroad tracks leading to the central train station in Berlin around 1910.

As it is for 3D printing, quite a few challenges crop up as every single mesh has to made into a watertight shell with no intersecting geometry. The 3D printer itself can print down to 0.5mm in detail, but it has trouble printing small details that has hanging negative y-axis geometry. Things one always has to have in mind when modelling it.
