The iteration of the mount that I received did solve the vibration issue I had with the acrylic mount, which had a fine crack in it which caused the vibration. There were two problems with the metal mount. The first was that the cutout for the controller module was too small for the controller unit. I was able to solve this with my Dremel tool and a carbide metal cutting wheel, and some files. The controller then fit. The second problem was that the metal mount is thinner than the acrylic one, and the controller did not snap into place, it flopped back and forth. I solved that problem with a few dabs of LocTite Super Glue gel. The set up is now working as it should with absolutely no noise what so ever.
