This is a replacement for Niko outlets and switches (EU outlets). Make sure to check the size in the second picture!
A step file is also provided to adapt the model to your needs. In my case, I cut part of it off to fit next to a kitchen backsplash.
I recommend printing the model standing to avoid the clicking features from breaking off. I also recommend a low layer height and sanding of the outside to get a nice finish.
