This is a design file of a case to accommodate your Raspberry Pi computer.
It is designed to be made from acrylic 3mm thick.
At the top and bottom are flexible because there is a design that gives this property.
Has openings in the sides to fit LEGO bricks.
It is very easy to assemble.
I posted several example photos of how to do it and also a video.
In the Ponoko USA you can make for about $ 12 + shipping. (only one color of acrylic)
Or, I'll I can do it in 2 color acrylic for $ 15 + shipping. (See my other articles for details.)
