  We study the problem of imposing Dirichlet-like boundary conditions along a
static spatial curve, in a planar Noncommutative Quantum Field Theory model.
After constructing interaction terms that impose the boundary conditions, we
discuss their implementation at the level of an interacting theory, with a
focus on their physical consequences, and the symmetries they preserve. We also
derive the effect they have on certain observables, like the Casimir energies.
