I'm looking for strips of plastic cable clip to tidily secure and rout multiple single 12vdc cables with about a 3mm external diameter.  Whatever I have needs to be robust and impervious to corrosion.

A product similar to what I want, but made for 4mm OD tubing:

Legri tube clip strip
Edit: picture added, hard to spot but this is a continuous strip of tube clips.
