Socket cover, AC line baby protection plug CEE 7/7

According to the plug system CEE 7/7, fhis socket cover fits into sockets of the type F, CEE 7/4 and type E.
Have a look on the picture to see which countries use this system.

I printed it with a 0.4 noozle, 0.25 per layer, Infill 20-25%, 4 top layers.
Fits very accurate and firmly into the CEE 7/4 (SCHUKO) socket, so print also the key to be able to remove it.
