Möckernstrasse Road for 3D printing

A 3D model set made specifically for a 3D printing project for the same customer as previous. These are road sections around the house called "Möckernstrasse" for now. These 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.

The interesting thing to note here is that the roads can be lifted off the road sections. Underneath you can see empty tracks. These tracks are for magnetic strips that will go along the entire road. These strips will magnetically control and propel small model cars along the roads, to further breathe life into the diorama.

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.
