The Raspberry Pi feels so naked with the board exposed to dust and the elements. Not to fear, since the Internet is teeming with people manufacturing and selling cases for the Pi. Me and my SO decided to make the popular Punnet DIY cardboard case for the Pi. If the Pi survives a few months as a HTPC, we might switch to a proper plastic case.
Making the Punnet case is pretty easy. Download and print the latest Mk1 version [PDF] of the case design to a A4 sheet of paper. Place the printed A4 sheet on top of a thick cardboard A4 sheet. Trace and cut out the case outline. Cut out the holes and make the folds. Use strong glue to stick the folds. We added thick cardboard to the bottom of the case to give it some heft and rigidity. Finally, place your Pi inside the Punnet case, connect back its wires and you are good to go! 😊
