The body structure is rather simple and solid, the only notable detail being
that it doesn’t use the standard grid.As we explained before, the lower layer is
separated by only one plate from the mid layer in order to make the 16t gears
match the worm gears.To be able to brace the chassis with vertical beams we also
had to adjust the distance between the mid and upper layers, so we used three
plates (one brick) instead of two (Figure 17.13).
