So there are plenty of cases out there for purchase, however, when we found one that we wanted in particular it was out of stock. So we took it upon ourselves to try to make the case we wanted on our Replicator.
This case is based on the acrylic laser cut case by Adafruit. Actually it is their laser cut file extruded 1/8" (3mm) to match the thickness of acrylic the design is based upon.
So just download the files and print! You will have to print case-c.stl twice to get the top and bottom.
Oh and you might be thinking why did we break the parts up into three files? So that if something happened during a print we would not have to start over from scratch.
You will have to do a little filing of the tabs to get them to fit in the slots but the case does work. I have had the Raspberry Pi on in the case for several hours while working on it and have not had any issues. It doesn't overheat or anything like that, but my Pi isn't overclocked or anything. So we can't make any promises.
