>>7761107The original mod is made by lengthening the Y joint with molten plastic, which is not that easy to do.
With the joints I showed you, you can freely adjust the size by cutting them where you want on the nub, making the step 3A pretty easy, safe and quick.
Just mesure the total length of the end with the 6mm joint (ball + peg) and add 2mm before cutting it on the nub.
