About this 3D model
Following the theme that a taller nut on the bed->leadscrew interface will help reduce backlash and wobble, here is a PLA printed assembly for use with the new Aluminium Platforms from Solidoodle. On the platform you will find 4 screw holes surrounding the leadscrew nut. Tap these out to M4. Print the nut using PLA as ABS will flex too much. PLA will also wear slightly better. Tap the center nut for 5/16th's and the 4 bolt holes for M4. Attach to the main lead screw and enjoy greatly reduced backlash and banding.
