13pin trailer connector cover

This is a 13pin connector cover for trailer / caravan electricity.
Pins in my connector on a caravan are always wet, when raining, so I made this simple but efficient cover.
It screws on to connector with 3 teeth.

It has 3 holes on sides, to put chain or some cable, so it is always near connector.

I printed it on Anycubic I3 Mega printer, resolution 0.2, but you can put whatever you like.
