  Using quantum Riemannian geometry, we solve for a Ricci=0 static
spherically-symmetric solution in 4D, with the $S^2$ at each $t,r$ a
noncommutative fuzzy sphere, finding a dimension jump with solutions having the
time and radial form of a classical 5D Tangherlini black hole. Thus, even a
small amount of angular noncommutativity leads to radically different radial
behaviour, modifying the Laplacian and the weak gravity limit. We likewise
provide a version of a 3D black hole with the $S^1$ at each $t,r$ now a
discrete circle $\Bbb Z_n$, with the time and radial form of the inside of a
classical 4D Schwarzschild black hole far from the horizon. We study the
Laplacian and the classical limit $\Bbb Z_n\to S^1$. We also study the 3D FLRW
model on $\Bbb R\times S^2$ with $S^2$ an expanding fuzzy sphere and find that
the Friedmann equation for the expansion is the classical 4D one for a closed
$\Bbb R\times S^3$ universe.
