Note: This is thing is not maintained on here any more, further development/support it will happen on its Youmagine page.
This is a case for the Bus Pirate v3.6 from Dangerous Prototypes/Seeedstudio.
It offers access to the header and the ICSP connector and a clear view on the 4 status LEDs.
The case was created with OpenSCAD, the source file is attached and can also be found on Github.
Print it at 0.2mm layers for the embossed OSHW logo to get proper strength.
