The Open Bench Logic Analyser is a cheap ($50) open source logic analyser board, which talks a standard (ie open) protocol to a PC client. Very useful!
As it's just a bare board, lots of people have designed and build their own case for it. Many are built with 3d printers and related methods. I did one too, but instead of going the real high tech route, I just used a slab of 6mm Perspex, cut into 3 pieces and with slots milled for the PCB to slide into.
