  We study two- and three-baryon systems with two units of charm looking for
possible bound states or resonances. All two-baryon interactions are
consistently derived from a constituent quark model tuned in the light-flavor
hadron phenomenology: spectra and interactions. The presence of the heavy
quarks makes the two-body interactions simpler than in the light-flavor sector.
Our results show a narrow two-body resonance with quantum numbers
$(I,J^P)=(0,0^+)$. It is located 6.2 MeV below the $\Sigma_c\Sigma_c$ threshold
and has a width of 4.7 MeV. The foregoing two-body state contributes to
generate a $N \Sigma_c\Sigma_c$ resonance with quantum numbers
$(I,J^P)=(1/2,1/2^+)$ and a separation energy of 0.2 MeV.
