Yet another case for the original Raspberry Pi model A and model B. There are a number of these out there already, but none seemed to fit my purpose, so here we go. The two models are the same, except that the top cover for model A has no hole for an ethernet connector. This design is made in OpenSCAD, so should be easy to modify as you see fit.

There are flags so you can optionally have a support shelf for the SD card, an opening for a camera module, openings for the LEDs and external access to the IO pins.

The case is made to snap together, but if you prefer, two countersunk screws can also be added. There is internal structure in the bottom, so you only have to remove a thin layer of plastic to expose the screw holes.

For a similar case for the model B+ and 2 model B, see http://www.thingiverse.com/thing:978990

Should be a straight forward print in PLA or other material, with for instance 20% infill. If you have issues with warping, a brim support is recommended.
