The 2-category of 2-modules/2-vector spaces.
Fix some commutative ring or more generally an E-infinity ring $R$. Then a basis for a 2-module/2-vector space over $R$ may be taken to be an $R$-associative algebra or more generally an $R$Mod-enriched category $\mathcal{A}$ (an algebras): the correspponding 2-vector space is the category of modules $Hom_{R Mod}(\mathcal{A}, R Mod)$. Then $2Mod_R$ is equivalently the 2-category whose
objects are $R$-algebras;
1-morphisms are bimodules,
2-morphisms are intertwiners.
In enriched category theory this is equivalently the 2-category of Mod${}_R$-enriched categories and profunctors between them. In this context one can write
or $2 Mod_R =$ Prof$(Mod_R)$ for this 2-category.
An algebra object in 2Mod${}_3$ is equivalently a sesquiunital sesquialgebra over $R$. This may be taken to be a basis for a 3-module/3-vector space over $R$.
