Daves Z Coupler

thingiverse

The original design aimed at creating a non-wobbling Z-coupler; however, it still exhibits slight wobbling. To mitigate this issue, allow the motor some freedom to move. A z-stabilizer/rod clamp from MakerGear's Prusa kit can be used for support by adding two nuts at each end. An optional set screw hole is available if desired, while the default shaft hole fits Ultimachine stepper shafts snugly.
