Simple Raspberry B+ Holder K8400 Vertex with power-button Case

I decided to create my own Raspberry holder for the K8400 printer, because i want a easy access to hdmi-, usb-, network-, etc. ports. Also the micro sd can easily changed from the front of the printer. Mounting the Pi overhead does not fit these requirements for me.
A nice feature is the Start/ Shutdown button with status LED.
