A bento box style case for the GM328 Mega328 LCR Tester. The one I bought is called "2015 LCD 12864 Mega328 Transistor Tester Diode Triode Capacitance LCR ESR Meter" and was bought here http://www.ebay.ca/itm/311343672563 A Lid is now included with letters and without. Print at whatever resolution you like. The circuit board can be screwed down onto the corner supports, but mark and drill screw holes first.
