M1070 uses the same grilles (and screw hole pattern) as the M1060 (NOT the M1060C, which is different). So any M1060 grille design will work with the M1070.
However, the cups of the M1070 are slightly larger so the the grilles will be inset from the edge of the cup compared to sitting flush on the M1060 cup. If that matters to you and you want the M1070 grille to sit flush with the edge, the M1070 grilles will need to be 108.7mm vs the 105.7mm of the M1060.
