  In a recent paper, the authors gave combinatorial formulas for the Laurent
expansions of super $\lambda$-lengths in a marked disk, generalizing
Schiffler's $T$-path formula. In the present paper, we give an alternate
combinatorial expression for these super $\lambda$-lengths in terms of double
dimer covers on snake graphs. This generalizes the dimer formulas of Musiker,
Schiffler, and Williams.
