This is a blank filler plate for any missing controller slot fillers you may have in your NetApp DS4246/DS4243. I made this as my diskshelf did not come with the filler plates. These fillers are needed to maximize airflow through the drive bays and out the PSU slots.

The plate fits in very tight so place the longer end nubbies into the square retaining holes on the NetApp and then snap in the shorter side. See image. Once snapped in, it may take a screwdriver to pry it back out.

Could use better finger hole domes, but they worked for my needs and nobody will see it anyway.

I recommend changing the seam position to one of the top or bottom sides as hiding it in a corner or on an end may cause the plate to be even tighter to install.
