I wanted to attach my led light, on the floating handle grip of the gopro.

So i did this mount. It fits handles of aproximately 35mm to 45m thick. Maybe even bigger, if you use longer bolts.

I used the standard mount of the gopro cameras. If your light requires bigger distance from the grip or the camera, you can print one or these!

There are 2 plates:

On the first one, i used 6.2mm holes, so you can add M6 bolts. I used butterfly nuts for easier tigthening.

On the second plate, you can insert M6 nuts, and  use M6 bolts.

You can print M6 knobs to make your life easier. I found these to be very nice !

I printed with 40% infill, and tree supports, using PETG.
 

Update: I added an stl with longer bracket, to keep more distance from the handle.

If you need a different, U-shape floating rig for your camera and light, check my other design here!
