Expo Dry Erase Marker set magnetic holder

I have a whiteboard without a marker tray. I bought the small Expo dry erase marker set that you see in the pictures from Amazon and wanted to be able to have a magnetic holder to keep it in that I could attach to the dry erase board. Pretty simple design, but it works for my needs. Hopefully it's useful to someone else.
