LED batten mount

I use LED batten lights to work on my car. They are better and cheaper than most automotive work lights. I needed a better way to place them under the car or engine bay, so designed a snap on mount. Stops the batten rolling over when flat on ground, and allows wedging it under stuff to hold above the engine bay etc.
Suits battens that are 30mm wide and have a notch along them about 8.5mm from the base.
My lights were from Bunnings...

There is an STL for a base for a remix, and my first mount with tab and holes.
