About this 3D model

I own an AUKEY USB 3.0 Hub 10 Ports (http://amzn.to/2pSonUA) which I wanted to put under my shelves. I created a hook for the USB hub and the power brick as well. Both item can be fastened with an M4 screw to the shelves. This object was made in Tinkercad. https://www.tinkercad.com/things/iJn9lwMZWwZ
