Couch LED strip holder

Hi,
I've got the problem, the LED strip fell from my couch. This strip is not stabel, laying around on the couch. Especially if someone sit down.
But now, with my couch-led-strip-holder, designed by myself, it's a pleasure to see how well it works.
Width is 10.5mm.

Of course, I printed in glowing in the dark filament. Additional I'm using glowing in the dark zip ties. But you need only a short piece for each holder.
Only to fix, that the strip can't go away.

I'm using it every 50cm in
