CNC2418 Z Axis

I have a CNC2418 and the X axis binds on the extreme RHS, didn't realize until was trying to mill a spoil board for the bed, the reason is the capture nut is epoxied in slightly off center. Anyway so after loads of looking found an old design, remixed it with correct dimensions (of mine). The capture nut is different on mine but this is a good first start. I'll use as a template to make another one. Sharing in case anyone else in situation. I have a 3D printer so will just print a new one.
