I just saw an article on this new childrens book for teaching kids about 3D Printing. It is http://www.leothemakerprince.com/

Does anyone know how useful it is, or for what ages it is meant for? I want to teach my son (10 years old) about 3D Printing because I think it's what he will be dealing with a lot in the future. Does anyone recommend this book for a 10 yr old?
