Ender 3 Lead Screw support (no extra hardware needed)
thingiverse
This remix of elmerohueso's lead screw support was created with no additional hardware required. To achieve this, the design was tweaked to provide more clearance for the extruder at full Z height. The updated support still accommodates both a lead screw knob and a small extruder knob. One skateboard (608) bearing is needed for assembly. The dimensions of this part are 1mm longer than elmerohueso's original design, with the center of the lead screw situated 21 mm from the frame's face. If you require longer or shorter versions, please leave a comment and they will be provided. To test the alignment of your lead screw, attach it to the print without the bearing and move the print head up and down. If the lead screw is not straight, a z-stepper spacer should be printed.
