Ender 3/Pro/V2 Z axis anti wobble nut - Direct Drive

Anti z-wobble squares

Metal Pins

Here you can find updated version of anti z-wobble. (probably last version :) and only for direct drive)

This design uses 32 additional metal pins (fi 2mm, length 8mm) on which steel balls are placed. Number of steel ball per layer was also doubled (4 per layer) to create full working plane.

Additional parts:

• M3 8mm screws - 4x
• 6x3mm magnets - 12x
• 4mm steel balls (I took mine from 628 bearing) - 8x

Metal pins - Length: 8mm, fi: 2mm - 32x, I have used cylindrical studs from BOSSARD: 1255622 BOSSARD Ø: 2mm; L: 8mm Assembly:
