The covariant parton model is generalized to describe quark correlators in a\nsystematic way. Previous results are reproduced for the T-even leading-twist\ntransverse momentum dependent parton distribution functions (TMDs), and for the\nfirst time all T-even twist-3 TMDs are evaluated in this model. We apply the\napproach to evaluate the fully unintegrated quark correlator which allows us to\nunderstand the model-specific relations between different TMDs. We verify the\nconsistency of the approach, present numerical results and compare to available\nTMD parametrizations.\n
