This is a light switch cover with grooves to use with a (Aqara) button holder. This is meant for the Gira 55 System.
I wanted to have the button to be easily removable for changing the battery.
I printed the cover without support and the button holder with supports.
The author remixed this model.
I used the Gira Light Switch Remix I made to implement grooves for the button holder slide-in. The original Light Switch Cover was made by @R2J3D.
I then used the Aqara 1P Button - Slide Wall Mount v1 in the Misc folder by @Volan to create a slide-in attachment for the light switch cover.
I did this to not have to print one piece with a lot of support but two pieces that can easily be connected. This way you could also design a holder for a different button and use the same cover.
