Batiment empilables, stackable buildings
In my series of stackable building floors, I updated one part in the A family, to remove a somewhat hard bridge.
For the various parts, refer to: (HO models)
Buildings A:

Buildings B:

Buildings C:

See also the bridges, tunnel entrances, a.s.o
Buildings E:

Use 55% scale factor to obtain N-scale (1:160) from these HO models.
The models print without any support or other printing help.
