Face plate for "Ramps Case"

I created a remix of faceplate from Ramps Case from 1sPiRe (it is awesome box man, thanks) for some improvements..

* Increased thickness to 2mm
* removed all extrusions from surface for the super flat look
* I replaced air holes with wider ones for better airflow.
* Increased Power Plug hole for Chinese ramps boards
* Added a hole for cables.

Note; Please ignore the lines in the image, its a bug of tinkercad and that lines actually does not shown in slicers
Enjoy
