I've been designing and 3D printing custom switchplate covers with PLA filament as I replace switches in my home with smart switches and it was brought to my attention that they may or may not meet NEC requirements (particularly whether or not they are made of combustible material). From what I've seen online, PLA doesn't seem to carry a flame like ABS or some other thermoplastics, but I'm not sure what is considered "combustible". Is this something I need to be concerned about? Thanks!
