AM8 Z-Motor-Holder for rigid coupler

thingiverse

If you want to use a rigid coupler instead of the spring coupler your threaded rod needs to be absolutely parallel to the z rod. To achieve this my version of the Z-Motor-Holder uses oblongs to allow a fine adjustment in the x plane I recommend using decouplers for the motor. The results are astonishing. No more wobble, shifts and other unwanted artifacts. Leveling is much more precise because the Z axis follows each motor move directly and without stretching or squeezing a spring. I only needed to change the right side because on the left it was already perfect. If you need a left side, simply mirror the STL in your slicer
