This is a housing for a typical Emergency Stop button for the Root 3 CNC project. It will bolt onto the existing pedestals on either the right or left sides.
It was printed in PLA with no supports. I used a paint pen to highlight the raised letters.
8/5/17 - I updated the front panel to tighten up the nut traps for a more snug fit. The Autodesk 123D source is also updated and provided. If the wording "STOP" is not appropriate for your nationality, it should be a simple matter to change.
11/20/17 - In the Thingiverse rendering there is an ugly hole in the face of the box which appears to be a manifold issue from the lettering. The model printed fine for me as well as for others, but regardless it looks like there might be an issue. I have created an alternate version with the lettering offset a bit from the face in the hopes that this will help if anyone has difficulty printing the first one.
