Having bought one of these (http://www.aliexpress.com/item/Free-Shipping-Small-12864-LCD-Transistor-Tester-Capacitance-ESR-Meter-Diode-Triode-MOS-LCR-NPN/2044583768.html), I couldn't leave it without a case so I designed this.

Printed in PLA with 0.2mm layers, no support.

You will also need 4x 24mm long M3 cap screws, 4x M3 nuts and a small piece of 1mm thick transparent plastic to cover the LCD. If you wish to use external power, then a 9V regulator (LM7809), a 3mm LED, some resistors for the LED (I used 480 Ohm), a capacitor to smooth the 9V and a DC adapter socket.
