I’m building a new video setup so I can make better videos while I work. One of the issues I had was the battery life of my camera: I could only film for 1.5h with one battery and then I would need to change it. To fix this problem, I designed a simple holder for a 20.000mAh external powerbank which I can hang from the camera tripod. Now I should be good to go for as long as my 256gb memory card can hold!
You can find the files for this model and more details on the powerbank here: https://www.printables.com/model/677223-wave-hanging-powerbank-holder
