This is a case for a Transistor Tester. This is based on the version provided in Hackerboxes Box #18. An optional knob is included to compensate for the short amount of the rotary knob sticking out.

Assembly

Lay Transistor Tester in bottom half. Connect three wires to connect probes to the tester. Either solder them to the solder pads or use the ZIF socket. Feed wires through the round hole in the top plate. Lay top plate on top of the base. I used 4-40 Machine Screws, 1 inch long, 4 total, to secure things together. Machine screws go through both halves of the case and the holes in the Transistor Tester. Optional, use a thread locker to keep nuts from screwing off.
