Robo R1 TR8 Lead Screw / Coupling Upgrade

For people who experience Z Axis ribbing and want a cheaper alternative to the "Official" Robo3D Z Axis upgrade, here is what you need. Print two copies of the model presented here. It is an adapter that will take a brass leadscrew nut and adapt it to fit the hexagon opening of the Robo3D X Idler. There is a very slight taper to the hex to help minimize backlash. With the adapter in place there is no loss of Z axis build height and the Auto-level still functions as normal.
