Just got my c setup plates and wheels in. But unfortunately I the openbuilds anti backlast nut won't fit my TR8*2 lead screw. I am trying to find a metal version or even just a way I can not have it riding through a plastic nut. Does anyone have a solution? Alternately, I would take a Tr8 2 plastic anti back lash nut. But I can't find one state to order.
