About this 3D model

The Orginal Z-Axxis Support can be adjustet with the normal screw nut. With a trapezoidal thread this is not possible. The endsupport at the top can not be adjusted with the spindel in place. My design ist much stronger and the Screw to fix the Bracket is accessible with the spindel in place, so you can adjust thr upper bearing to unload the stepper Motor. The new Version V1 with a diameter of 22.1 mm should fit perfect with a 608 Ball bearing. I also added the Profile of the Aluminium Profile
