Abstract
Using the theory of dimer models Broomhead proved that every 3-dimensional Gorenstein affine toric variety Spec admits a toric non-commutative crepant resolution (NCCR). We give an alternative proof of this result by constructing a tilting bundle on a (stacky) crepant resolution of Spec using standard toric methods. Our proof does not use dimer models.
