Made some small remixes.

The plug received a cable hole, so I can route the usb cable to the outside, and still plug the hole.

The small clamps got modified, so there is now a little piece to lightly press on the led strip.

I had the problem that the adhesion of the strip wasn't so good one some part. And i reduced the width to 5mm from 10mm.

I removed infill and top/bottom surfaces. And printed with 1 and 2 walls.

With 1 wall was very light and flexible, but still resistant. It was holding well, but the upper part was a bit to flexible for my taste.

So I used the one with 2 walls, which was just perfect. Solid fit and very good grip.
