This design is a button guard for the Litter-Robot 3. It is very easy to accidentally press the "empty all litter" button rather than manually cycling the machine so this covers it, making it impossible to press with a finger. Instead, you press the button underneath through the small hole in the guard with a pencil or similar stylus. It should fit loosely enough that it doesn't bind to the button but tightly enough to stay put.

A STEP version is included to allow for easy customization.

Please note that pressing firmly on the button guard (or anywhere on the control panel for that matter) can trigger the Litter-Robot's weight-based sensor. It can be canceled by pressing the "Reset" button.

Guard should fit loosely enough that it doesn't bind to the button but tightly enough to stay put, your printer may vary.

A chamfer was used around the guard's edge rather than a fillet so the button can be printed without supports.
