This is designed as a replacement/alternate part as the rubbery screw caps they supplied do not hold, if you barely breathe or look at them or slightly brush them they fell off so I wanted to replace them completely. This plate looks like it's meant to be there and provides same effect of blocking stuff from getting in the screw holes.

should be fairly tight to hold but not so tight to not be removable. Only about .05 mm gap between existing hole and the pegs on the plate total.
