if when you print the dragon and there is a error in print cut off the chain with the error and then to connect the chains back together cut the horizontal chain so there is a small gap where you put the vertical chain and it should be connected (please note this is a solution for petg users only because of petgs strong and flexible properties) and if you wait for the v2 there hopefully will have no errors

 - use supports at 0% angle

- be careful this thing is so sharp so don't use it as a weapon
