A new top cover for the IKEA SYMFONISK sound controller. I use it to dim lights however (homeassistant + zigbee). Just remove the 3 screws and carefully take the controler apart. It might be possible to just pull the original cover from the controller, however I haven't tried that. There is no need to move the soft circular thingy from the original top cover as it works fine without it. The clamping parts within the cover can be a bit brittle, but it works fine. After assembling the controller again (without the cover) you can just push the top on and it should work fine.
In the picture I have printed it in light oak PLA from Addnorth and then rubbed the surface with 100grit sandpaper and stained it using a dark oak stain.
