CEE Socket Cover for Caravan

The cover for the CEE socket on my caravan broke off. For this reason, I designed and printed a new one. Initial results are satisfactory so far. I printed it for myself from PETG, but I think ASA might be better. For fastening, I used an M4x25mm screw. Longer ones also work, as can be seen in the picture. An M4 thread was intentionally not designed. The M4 screw goes in a bit harder, but it holds much better.  

If you liked the model, I would appreciate a like or boost. :)
