This is a standalone Raspberry Pi case with integrated power supply and display. As well as the printable parts there is some circuitry and software involved.
Full instructions are available on the project page on my site - http://thegaragelab.com/projects/the-pistation.html
This is not really a 'plug and play' type of project - you will have to modify it to suit your needs and the components you have available. I've done my best to provide everything (source for the printable components, schematics and PCB layouts for the electronics and source code for software to drive it) to make it as easy as possible.
I'm more than happy to answer questions left in comments here or on my site and I'd love to hear about your specific implementation and changes as well. I'm more than happy to host or link to articles about your derivatives of the project too - just leave a request in the comments.
Good luck and I hope this project is helpful to you.
