Wall switch warning cover (parametric)

This is a cover for wall switches to prevent your children, spouse, cleaning personnel, pupils, parents, everyone from accidentally switching the power outlet with your 3D-Printer/computer/whatever off without thinking about it first.
However it does not render the wall switch completely useless.

You can resize it to your needs in FreeCAD by changing the values in the spreadsheet.
After that it should fit perfectly to your switch and stay there due to the small lip in the back.

STL fits to 80x80x19 switch
