(Be sure to check out the matching outlet cover)
One file is blank so you can make your own opening(s).
The other file is for a single small US sized light switch.
The one in the picture has the edge trimmed off because it had to be installed so close to the door trim.
You can print it in whatever quality/infill you want, but it does take a long time, so watch out :)
We printed in white ABS and I painted it brown and "washed" it with gold paint mixed with water.
The bottom center part is empty and definitely needs supports so the top will print.
