We start from a recently favored picture in which the Λc(2940) and Λc(2910) correspond mostly to ND* bound states with JP=1/2−,3/2− respectively, and then add a D as a third particle, looking for the possible binding of the DND* three-body system within the framework of the fixed center approximation. We find that the system is bound with respect to the corresponding Λc(2940)D, Λc(2910)D thresholds with a binding of about 60 MeV and a width of about 90 MeV.
