This a smaller version of the Pi Box. Many people liked the idea of the original Pi Box, but didn't have a large enough print bed to actually print it. Here is a smaller version that is designed for the Raspberry Pi B+ along with a few variations that will hopefully spice things up.

Besides your Raspberry Pi B+ you'll want the following.
External USB hard drive
One SD card (minimum 4GB class 4)
One short panel mounted hdmi cable (978)
One short panel mounted LAN cable (909)
One short panel mounted USB Cable (908)
One short micro usb male female cable extension
One 16mm switch (917)
One 5V 2A micro USB transformer

The numbers above in parentheses are part numbers at www.adafruit.com and are given as examples. You can almost always find them cheaper on either Amazon or Ebay.

I'd like to warn everyone that I have not printed this. This design is for all the people who liked the Pi Box, but couldn't print it without getting a much larger print base. Any comments or concern would be greatly appreciated.
