This is my own version of an adapter for a better fit of a europlug into a schuko socket. (CEE 7/16 or CEE 7/17 plug into a CEE 7/3 or a CEE 7/5 socket).
This adapter should work for socket in most European countries using those CEE 7 sockets.

For the printing:

Nothing special here, just standard Bambu PLA Basic profile

0,20mm layers

no support

no brim

3 walls and 25% cubic inlay (just because I like to print strong models and it doesn't matter on such a small model)
