I was looking to print a schuko socket and the one from Bakajohn not only prints without supports, but you can add different skirts around the main socket, which I found very amusing.

His socket prints very well but the socket holes are a bit too tight. Not only there are thicker metallic schuko plugs, but also the connectors in the back are not always completely aligned.

So I just made the connector holes a bit bigger and added a fillet, and made a new skirt for my project.

Ευχαριστώ bakajohn :)
