Gimbal handle

This is a handle I made in order to convert a quadcopter gimbal to a hand gimbal.

This is a first design, and it has a rough finish, but is fully functional.

If you want to use it, keep in mind that the pieces are designed to fit my gimbal and my battery. Other gimbal models or batteries maybe doesn't fit.
This is the gimbal I used:

And this is the battery:

There is a hole in the top cover tu put a switch (https://www.amazon.com/20pcs-Black-Switch-Electronic-Projects/dp/B008R50AA0), but I haven't time to put it before the test.

The top cover is thought for leave it in place, using the bottom one to take out the battery and charge it.

Also i tried to do a little box to cover the gimbal electronics (you can see in the photo), but the result was a crap and I had to use hot glue to keep it i place, so better if I don't share it

The mounting holes are thouht to use M3 screws
