We compute the spectrum of gluonic screening-masses in the $0^{++}$ channelof quenched 3d Yang-Mills theory near the phase-transition. Ourfinite-temperature lattice simulations are performed at scaling region, usingstate-of-art techniques for thermalization and spectroscopy, which allows forthorough data extrapolations to thermodynamic limit. Ratios amongmass-excitations with the same quantum numbers on the gauge theory, 2d Isingand $\lambda\phi^{4}$ models are compared, resulting in a nice agreement withpredictions from universality. In addition, a gauge-to-scalar mapping,previously employed to fit QCD Green's functions at deep IR, is verified todynamically describe these universal spectroscopic patterns
