Prusa Enclosure Lighting, Ikea Ledburg LED Holder

From the Prusa Enclosure spares, use a M4 screw with to square nut to mount. 

Insert the square nut into slot of the plastic holder and put the screw in from the outer top wall via one of the empty holes. In my setup I ran this diagionally to allow for the cables to be tidy at the back with zipties.
