Normally if you are installing this you are not worried about turning the actual switch off at all. However, what if there were ever a need for you to? That is why I modified his design to add a side switch to turn the physical switch off if you needed to reset the lights for some reason. This way you won't have to remove anything to get to the physical switch.
This is for the philips hue switch here - https://amzn.to/3LaMje5

Printed main box at 25 Infill with Supports at 50.
Be careful when removing supports from guide rails inside as the guide rails inside are fragile.
The slider piece that inserts into the side is printing vertically with or without supports. I placed a couple bars for support within the slider so you shouldn't have to but it isn't an issue if you do print with supports.
On the slide on pieces just print a two horizontally.

Assembly:
Print out one hue switch mount 25infill or more, one hue switch mount slider 100infill, and 2 slideon pieces 100infill.
Take the slider and insert partially into side of mount, add one slideon to slider then push slider through the rails and add another slideon to the end past the rails.
This may not be needed but I feel it would just be more stable with something at the beginning and end of the slider to make it more stable.
Add hot glue around the slideon pieces to keep them secure in place.
