Micro SD extension cable case

I purchased a cheap Micro SD extension cable from Ebay (£1.59 http://www.ebay.co.uk/itm/231567666416?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT ) and needed some method of attaching to my Anet A8. As I had already installed the upper frame supports I needed a design that could clip onto this extra width. Not having found anything suitable for my needs I decided to design and build my own.
The two smaller cases enclose the micro SD card reader firmly. This enclosure then slots in to the larger case. This is a tight fit.
The unit can then attached as shown.
