This is printable fold-up case for the Raspberry Pi. It works best with transparent mylar overhead projector (OHP) sheets, or thick paper (cardboard). I prefer a transparent case, so the computer is protected but still visible:

You may need to change the print settings (disable zoom). Print the case, and then check if the size matches the device, before you start cutting.
If you want to create a transparent case, you might want to print on regular paper, and then tape the paper on the transparent sheet. Don't try to cut without using adhesive tape, as the sheets will move (as I had to learn).
Fold as many sides as possible before cutting, specially at the ethernet connector. Use a box cutter if possible (not scissors). Cut the connector holes first before cutting the lines.
When done cutting, fold the case so each fold is about 90 degree. Then fold back, and start assembling. You need to start at the 'anchor' (on top of the SD card, just left of the Raspberry Pi logo). Then the USB connector, the bottom of the case, the video out / microphone side, and finally the HDMI side. The "double flap" might be a bit tricky to close, but that way it will stay closed.
Do not squeeze the case. Instead, hold the box on top of your hand. To plug in cables or to insert the SD card, push at the opposite end of the computer. To detach a cables, place a finger next to the connector. The only possible exceptions are USB and ethernet, as those connectors are (almost) as thick as the case.
