Thank you very much for your Fantastic job!
I was looking for drawing of paper case, then hit punnet.
When I assembled your case, I found a margin touching RCA Video Connector.
I add just a little bit changes:
I changed position of hinge, because of glue margin touching RCA Video connector.
I added small cut on margin, because of holding top cover and easy to open.
I changed shape of top hole, and broken line.
I changed some label text.
I will soon teach programing for kids with RaspberryPi, and I also want kids to make Pi Case by their hand.
And I also want to cut the case by cutting Plotter(Silhouette Studio) for kaizen prototyping, so I traced and convert your PDF to Silhouette Studio file with above changes.
Here is link to PDF and Silhouette Studio files
