Monitor headphone hanger

My version of a monitor headphone hanger. This is the first time I ever creating something using google sketch up and really anything cad for that matter. I designed it on the thicker side as I just wanted it to look substantial and to be a little more durable than thinner parts. Also google sketch up dose not lend well to making very small objects.

The hook has an approximate gap of 39mm and is 11mm thick with a 10mm kick up and is 5mm thick . It covers 50x50mm of the corner edge and the edge you see is 20mm across the top and 17mm down the side. The lip that rests on top of the monitor and down the side is 14mm.

Any good double side tape will work I would use as thin as possible that your set up allows to remove a illusion of it floating.
