Hey, i would be willing to tet these files. i actually just took my machine apart, and discovered that yet another rigid z had broken. so i will be reprinting the Z assembly anyway. my email is [email protected]. i am also reprinting the corners since i am donatine the originals to another build for my sons school. i tried the totem corners, but they dont fit the conduit i have? even printed the US version and i tested a UE version one is to big, the other to small. so i am going back and trying your new corners.
