I have a set of plates from Chris at blue ox for a sphinx with hg15 linear rails on all axis they are not used and high quality I decided to go with a different style build I also have all the appropriate lead screws lead screws nut blocks z axis plates rails and bearing blocks and more everything needed including the c beams and other extrusions this is basically a complete kit to build the sphinx minus the steppers and electronics these parts as you know were not cheap so I don't want them to sit and go to waste if your interested email me or leave a message here [email protected]
