Some more pictures:
The chassis and how are fitted the two partitions (in and outside)
14 pieces make the chassis; they are from different size of spacing; her is the longest:
and now the same printed in 3D by the guy I told you about earlier:
Here is the adjustment of some pieces in the middle of the car; all fit together well! phew!!!
Last one, the first piece I made yesterday: it's the rest room partitions (lower level)
See you later for the specification; files must be too large..
