About this 3D model
This is a sleeve / cover for the EVE Energy plug (EU - Schuko). I used the newer version that has thread support - but I guess the older version might be identical in size. The cover simply slides over the plug and locks into place. Removal might be no so easy, but that depends on your print quality and accuracy for dimensions. Pressing the button on the plug should still be possible but there is no special feature on the model to support this. The flexing of the cover should be sufficient.
