Mains cable clip

Mains cable clip to stop an extension reel unwinding.
One side has bigger fillet rads and is the side that should be used every time. The other side has smaller rads and goes on the cable near the plug. It is harder to get on and off, but that is by design. Be careful to deburr the inside curves to avoid cutting into the cable insulation.
Was designed for a cable with 7.7mm diameter. Can be scaled in your slicer software to suit.
