mm ill try the universal extender. does it need aluminum? I use gear or saw mold becouse they need more metal. But, still, u need to convert the back to plates or rods. The purpose of this is a full automation so using pincers or puring additional material are not helpfull.
EDIT: I saw the recipe of the universal extender… and they are quite hard to craft because of the circuits. In dont think it is the right soultion here since all this sould be for early game.
