TP-Link TL-SG116 mounting bracket

I have a drop ceiling in my hallway so I mounted my network equipment upside down on a piece of plywood.  This switch seemed a bit heavy and I didn't trust the screws in the stock mounting slots to hold it up so I quickly made up this bracket to make sure that my switch doesn't end up on my head during a trip to the bathroom.  Not sure if this will be of use to anyone else but here it is just in case.
