Non-commutative crepant resolutions for some toric singularities. II

Using the theory of dimer models Broomhead proved that every 3-dimensional Gorenstein aftine tonic variety Spec R admits a tonic 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 R using standard tonic methods. Our proof does not use dimer models.
