WATCH: The spin cube on a key ring that could rival fidget spinners
An ambitious designer who hopes to compete with fidget spinners has invented a more compact and transportable version - which can fit on to a key ring.
Andy Lewis, 58, previously worked as an electrical engineer but for the last few years has been working as a 3D designer.
He says he developed almost 20 alternatives to the fidget spinner in recent years before he settled on his Spin Cube contraption.
