Chapter Excerpts from the "NXT Zoo Book"
Shown here is the stegosaurus. The link to three chapter excerpts is here.
There are numerous parts substitutions listed throughout the book. (For example, the book shows how the "scales" of the stegosaurus can be made in different ways). There are also parts packs that make building easier. (The education resource set is a helpful adjunct for seven of the nine models).
More details regarding parts will be in a forthcoming post.
