When working on my GCSE computer science course work, which involved using Raspberry Pis I was asked to create a case which could be laser cut from card for the rest of the class to use. I found this case on the internet, which itself was based on this case for the Raspberry Pi Model B, unfortunately it was a bitmap PDF file which would not have worked very well with the laser cutter. To combat this I used the PDF as a template and drew over the top of it in 2D Design, I cut the outline and engraved the fold lines and text and also I improved the ventilation hole with the Raspberry Pi logo.
Step 1: Download the Files
I have included the 2D Design File and a DXF file (if you need it in any other formats let me know in the comments and I will see what I can do!). Download them and laser cut to your hearts content.
ALTERNATIVELY just print the included PDF and carefully cut it out with a craft knife. (make sure to print as actual size and not fit to page)
Step 2: Assemble the Case
Fold all of the tabs and edges along the scored lines and glue the smaller side tabs into place (any glue will work) forming a box with the lid open. Let it dry and insert the Raspberry Pi, the lid can then be glued into place or just tucked in to provide easy access to the pi.
Epilog Contest: If I owned my own laser cutter I would of course laser cut Raspberry Pi cases and I would make lots of instructables about making things with it!
