This box is for indoor use only. It is not sealed or waterproof.

The OpenScad file is included.

Edit the variables at the top of the scad file to suit your needs.
OpenScad creates a warning that the case body is not manifold, but this is nothing to be concerned about. It is a warning for the power cable holes in the side of the box. The project prints fine. You can ignore the warning.

Be sure to download the Write.scad files as this project prints text on the breaker guard.
The files are included with this project or can be found online at .
