This is a light switch cover designed to prevent access to a light switch (i.e. for when a smart light is in use). It is intended to fit a standard Australian light switch.
Included are two different sizes, one intended to fit a switch cover with a width of 73.5mm and one a little larger at 75.5mm.
A little double sided tape is recommended to keep them secure.
This is a remodel of wamfox's “Light Switch Cover (Clipsal) Australia” (https://www.thingiverse.com/thing:3924959). Specifically, the wifi logo was not included in this remodel, as it tended to weaken the print in that area. As well as including the slightly larger size as an option.
