improved switch box design

I made design improvements to the electrical box. I found a problem with the electrical box when the walls of the normal electrical box didn't have a hole, making it difficult to install and having to drill a hole in the electrical box, so I made a design improvement by adding a hole connecting the electrical box by increasing the distance. efficiency and material thickness files can be downloaded in solidworks and STL files and can be printed using a 3D printer machine with ABS PLA plastic and other materials
