Wall Hole Cover – Light Switch Relocation

When I moved a light switch, I was left with an unsightly hole in the wall where the old electrical box used to be. Instead of doing a full patch and repaint job, I designed and 3D printed this simple snap-in wall cover.
This part is designed to cleanly cover standard switch box holes (⌀ 67 mm), often left behind after renovations or relocations.
The cover includes:

- A circular insert that fits into the wall hole,
- A square faceplate to conceal the edges around the hole.
