Box for LED String Lights / Lightbox 2AA

Hi, I designed an Box which fits the Battery-Boxes of those LED-String-Lights.My box measurements are inside: 38mm (width) x 71.5mm (height) x 23mm (depth) and fits those String Light Boxes with 2 AA Batteries.The Top needs to be puttet on the box without force, it fits really great :) It can be taped, or screwed (there is a hole on the back) onto a wall :)
