  Commutator blueprints can be seen as blueprints for constructing RGD-systems
over $\mathbb{F}_2$ with prescribed commutation relations. In this paper we
construct several families of Weyl-invariant commutator blueprints, mostly of
universal type. Together with the main result of \cite{BiRGD} we obtain new
examples of exotic RGD-systems of universal type over $\mathbb{F}_2$.
