Tarot 680 Pro arm folding joint item

thingiverse

One arm of my Tarot 680 Pro folded itself during flight because the arm folding joint item was broken and the drone crashed. After dismount of the lower center plate I found that all 6 arms had damaged joints with one arm completely loose and 5 arms had a crack at the lower or upper screw. This joint is originally so badly designed that it cannot take hardly any load from an accident affecting the arms. Thus I decided to redesign it to be stronger and also have more space for cables going through it. My design is made for printing with TPE. This results is a super strong joint which also can flex a little if arms are hit during some kind of accident. All six arms of my Tarot 680 Pro now have these joints and it has worked very well so far.
