  We derive the full spacetime metric of a generalized uncertainty-inspired
quantum black hole. We examine a previous model of the interior in this
approach and show that extending its metric to the full spacetime leads to
serious issues in the asymptotic region. To remedy this, we introduce an
"improved scheme" mimicking a similar prescription used in loop quantum
gravity, where the quantum parameters are made momentum-dependent. Under this
scheme, we rework the interior of the black hole and extend it to the full
spacetime. We find that the resulting metric is asymptotically flat and its
associated Kretschmann scalar is regular everywhere. We also show that the null
expansion and Raychaudhuri equation are regular everywhere in this spacetime,
implying that the classical singularity is resolved.
