My dad needed a new light switch and so he bought one and found that it doesn't fit in the wall without a gap being shown. This gap filler avoids the need to break part of the wall and allows the user to put the light switch in without breaking or harming the wall. My dad was very pleased with the result and i wanted to share it with the community on MakerWorld. I hope you enjoy this project and find it useful and dont forget to leave a comment and tell me how to improve next time!
