I purchased a fixer Upper house and some electrical boxes were installed badly. Some stick out and others are too recessed.
This is the spacer for the ones that are sticking out to far. I will be making another spacer for the ones that are too recessed as well.
Note... You may need longer screws but those are easily available at your local hardware store.[
yours pla is fine
make sure to flip the STL file on its front face so you don't need supports
