I got bored and had some spare parts, decided to make a light out of an empty spool. 

The file contains a diffuser, wall mount, drawer (for components and wiring) and a  CR2032 battery compartment (literally just a box which friction holds 4x CR2032 batteries.) 

The LED strip i used needed a 12v supply so i had 4x 3v 2032 batteries in series with a switch to turn the lights on or off.
