Simple IKEA Jansjo mounting bracket

A simple bracket for IKEA's awesome Jansjo LED gooseneck lamp.

The Jansjo lamp is perfect for focused lighting, I use a couple on my workbench to illuminate my printbed and shining a little extra light on electronics etc.

Unfortunately the desk version takes up valuable bench space and the clip version requires something to clip to (and is also much more expensive).

This thing is a quick hack to remedy that.
