Velcro strips can be found in rolled form with several width sizes in market. They are very useful to tie up loose cables of any sort. You can simply roll a cut piece of Velcro strip onto a cable and wrap it up. But when you untie it, Velcro come loose which is not so good solution.
These tiny clips can conveniently be used to attach the Velcro strip onto the cable on hand. The clips presented here are only for 10mm and 13mm wide strips. Both parts of the clips have thorns inside to keep strip in its place. They can be printed with material like PLA, ABS, PETG etc. in a very short time. Flexible filament material is not suitable for this model.
You can watch the following video for assembling the clips on cables.
