I use an Insta360 x5 and x3 on a 5 foot "selfie" stick. They get to be a burden if you have to hold them out that far for too long. So, I designed this counterweight that fastens to the 1/4-20 threads on the bottom end of it. it makes it noticeably better, balance-wise. It's just a simple container with a lid and a tube up the middle for the bolt. I printed mine with a fuzzy skin, because I like the look of it. I also use a fastener that's too long with a nut so that if I rest it on the ground, the bolt touches and not the counterweight. I fill it with BBs. The amount you use, depends on the weight of the camera.
