Inspired from other cases I created a fully customizable case with OpenSCAD. You can also add a logo as dxf, please check the source. Therefore I uploaded the Source twice where the difference is only:
``logo_use_it=true;``
``use_ventilation=false;``

It is also possible to lock the case with a little screw on the left side. Simply drill hole between the case and the front cover. Please remove your Raspberry Pi 2 first ;-)

If you have Questions please post it.
