articulated led light for shelves

I needed some light on the 3D printer instead of always having to turn on the camera, so I bought this LED bar (I have to say I was wrong to buy, I did not realize that it was the one with the built-in battery xD) and I designed this lamp support system. Being articulated hides occupying little space under the shelf and cats have no reason to play with it.

What I used:
2 pcs M3 x 15 mm with nut
2 screws for fixing on the shelf
