I needed an in line solution for power monitoring so threw this model together to fit a Shelly module.

Paused mid print to change colour so that I could have nice looking text. As you can see it is for monitoring the power usage of my Electric Vehicle. There is a small tab on the lid on one side and its secured with two M4 screws on the other side.

I used some threaded inserts for the first time and I am super happy with how they turned out. The plug has an RCD which is great if I ever need to use my charger outdoors, even though I doubt it will happen.
