Tattu 850mAh 4S LiPo Protector (light)

Building a drone under 250g requires every gram to count. To achieve this goal, I made some modifications to shave off weight from the original design. First, I closed the bottom of the drone with only two layers, which should provide sufficient protection for the battery against abrasion and impacts if printed correctly. On my first attempt, I decided to open up cable holes on all sides to save weight and avoid having to think about it. This approach allowed me to simplify the design. However, on the second model, I took it a step further by reversing the side tab, which was previously in the way of the cable. While it doesn't feel perfect yet, this adjustment has resulted in a better fit for the battery.
