That's tricky with a Nema 23/24 motor since the shaft is not long enough to accomodate two pulleys for 15mm wide belts. You could bolt two pulleys together, so one would overhang on the shaft, but that might be a bit much force for the motor bearings. Adding an extra bearing would sort that, but if you don't have access to a lathe or milling machine that gets tricky.
