This is a 18mm tick shelf mount for a "25CM 5W Dimmable 25 SMD 5152 Super Bright Micro USB LED Strip Lights" from Banggood: http://www.banggood.com/25CM-5W-Warm-White-Dimmable-25-SMD-5152-Super-Bright-Micro-USB-LED-Strip-Lights-p-972520.html Is very easy to assembly and does not require screws or adhesive. I'm using this to help me see my radio transceiver buttons when in the dark. The microUSB connector cable is hidden inside the mount. The holder modules are reversible. You can mount the cable on the left or right side as you wish.Just print the 4 components and assemble them as in the pictures.
