Beikell USB hub holder

I wanted to stick the Beikell USB hub to the bottom of my monitor. The rounded shape made this impossible, so I designed this holder.

The first attempt without holder with PowerStrips did not last long, because the contact area is too small due to the convex / curved shape. The holder is needed in pairs and has cutouts for the cable and the last USB port, respectively.
I've bought the hub at Amazon.de
