This is a replacement switch for a Timer Plug Socket Outlet that I was given to fix cuz the original broke. In the back I can see it's model TS-MD31 from Intertek but when I searched it seems that different companies are selling the same thing. Do refer to the images to determine if it is right for you.

I did use a bit of the empty space to make it more rigged and made sure it is printable without supports.
