Waveshare 5inch HDMI LCD (B) Simple Case

I bought one of these displays from Amazon, http://www.amazon.com/gp/product/B00WMHSCKO?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00, but I could not find a case that would work with it.
Recently I got a copy of Fusion 360 and watch the video on making and case for the Arduino.
So I thought it would give it a go. And this is what I have managed to create so far.
By the way I included a 3D printable image of the LCD and the connectors in case you want check you printer accuracy to mine before you build the case.
