Linear actutator / test slider

This is 3D printed test slider / linear actuator. I built it to test how Igus linear bearings work with cheap steel linear guide shafts for my 3D printer project. Leadscrew on drive end is fully supported, on free end axial motion is allowed. Nut is anti-backlash. Screw must be machined according to drawing attached. Linear bearings are Igus WJ200UM-01-10.
