Geeetech i3x Acrylic - Front Box for 19mm LED Switch

A remix of the front box stepper mount tailored to the Geeetech i3X, to suit a standard 19mm round switch [like these](http://www.12voltplanet.co.uk/user/products/large/Rocker_switches_1_way_LED_dot_PNT.jpg), for example.


the keyhole slot (square section of the hole) is deliberately undersized (1mm x 1mm) to ensure a snug fit, but may require filing to achieve the correct sized aperture.
