A simple cable clip suitable for car mobile phone charger, dash cam cables etc
Suitable for cables with an overall diameter of around 3mm, can be up-scaled to suit larger diameter cables.
Stick down with double sided sticky tape, the foam type works best.
Very handy in an emergency and is a very quick print.
I printed them lying flat using supports that are easily removed but it may be possible to print standing up, eliminating the need for supports.
