Action Cam Gimball

I put this together because the gimball I bought works well for more heavy cameras but not for my action cams - they are too light.
I currently use it with my YI 4K and it works very well. It required a fair amount of fine tuning (by altering the exact position of the camera and moving the weight up or down) to make sure it is really stable and you don't get sea sick from the movement.

For convenience I put most parts in one STL, which is the handle, the middle part, and one half of the bearings holder.
You need the bearing holder twice, upper and lower half. Insert the bearings onto the handle and the middle part. Insert all into the first half and glue the second half to it.

Afterwards use a 6mm threaded rod (maybe 20 cm) and some nuts (at least 4). You also need a weight to go onto the other end of the rod. It should have roughly the same weight as the camera, but you can adjust it by moving it on the bar up or down.

The camera goes onto the base plate which is printed as
