One of my friends crashed his drone and as a result one arm broke. So i designed two parts that support the two broken pieces of the drone. Its operational as before. One of my concerns was the additional weight of the printed parts so i designed one more part as an additional weight for the other 3 arms of the drone in order to be balanced. The flying tests showed that there was no need for the additional weights. The whole assembly was done using 4 m3 screws with their secure nuts, and the overal weight of the assembly was approximately 40 grams
