This model holds your Ikea Tradfri switch in place. First I created 1 model with an angular exterior (which in my case holds the switch even better). For other folks I also created ones with a flat top.
The metal part you can put inside the holder.
When you double-sided-tape the metal part to the bottom of the holder it may be quite difficult to get it out but that's a different problem that we may have to deal with in a later stage.
The author remixed this model.
