I made this case for the Bus Blaster version 2.5. It's a JTAG debugger from Dangerous Prototypes. The license for the case is CC0 and the ViaCad file (ViaCad Pro 7) is in the attachments as well. After printing, sandpaper the two faces of the case who are located together when the case is build together till the PCB fits proper. Then cutting screw threads if you like. And maybe the countersunks and other things must be rework a little bit.
