Led Strip Box without battery

Obi Led strip powered by 4 AA batteries. I wanted to use it with RPi, so I remade it to USB connector and didn't want to damage the original housing with the battery holder.Designed to be printed with 0.6mm nozzle. For 0.4mm nozzle, you might need to set the line width little higher (0.43mm).For me it holds without a screw, but there is a possibility to secure it with a M2 Mini Screw Round Pan Head This is my first design
