Domonoky designed a very nice 3D printable case for the Open Bench Logic Sniffer. He then printed it using different colors of PLA fed into the printer to get a multi-colored print. It is even customized with a name on the top. This is a very nice example of using 3D printing to make custom enclosures for your electronics projects.
