Initial idea for caravan

The tensegrity model I did before was jointed with six rods with the same length. For the over all shape of my caravan, I decided to keep the consistancy with my jewellerybox, but with some developments.

The two images above showed the initial shape of my caravan. I have extened the length of the two rods at the top and bottom, which changed the shape a little bit, it's no longer a ball shape like the previous model.
Also I have decided to change each rod into 90 degrees angle instead of being straight, so that the internal space of the caravan will much bigger.
