Holder Base for Lampshade on String / Wire

I had an old lampshade plugged into a lamp and a cable but I had nowhere to hang it on, so I drew this quick holder/base for holding the lampshade in place so that I could use the lampshade I had already setup. I don't remember where I got this lampshade, but it is not included in the model. I also used some zip ties to hold the cable close to the body of the holder so that it doesn't move out of place.
