Prusa clone Z axis stepper extender

This print was designed to create a necessary space needed to retract motor shaft with printed Self-centering tr8 nut which collide with X axis endstop - rendering not to home Z axis.
In the original Prusa part there are steppers with integrated leadscrew and creating clone with those parts and detached leadscrew with printed coupling was not suitable. Until this mod ;)


Note: You need to mirror this part in slicer to create for other stepper.
