To stop the ratttle on my MMR royal I cut some plastic shims using .20 thick (1/2mm) plastic. The shims about 1/4 inch wide by 2.5 inches. I then tucked them between wood cabinet and bottom of the plastic trim. About three or four on each side. This seemed to raise the glass enough to stop the rattling.
Did the same on my AFMr but used .30 inch thick plastic. About the thickness of a credit card.
Pictures are before they are tucked under the plastic. Also used black sharpie to hide white plastic edges.
