Compact Magnetic Z Anti-Wobble Nut

Compact Magnetic Z Anti-Wobble Nut

A compact magnetic Z anti-wobble mechanism inspired by the WobbleX/Graham concept.

My goal was to reduce the overall assembly height while keeping the floating anti-wobble principle. Instead of making everything printable, this design combines laser-cut steel plates with 3D printed parts to create a compact and rigid mechanism.

If you have access to a laser cutter (or a local service), the metal parts are inexpensive to manufacture and easy to assemble.

Features

• Low-profile design

• Floating magnetic anti-wobble mechanism

• Hybrid laser-cut + 3D printed construction

• Designed around readily available hardware

• DXF and CAD included

Bill of Materials

• 2 mm steel sheet (laser cut)

• 6 mm steel balls

• 3 × 2 mm neodymium magnets

• M3 hardware

• CA glue or epoxy

• Printed ABS or ASA parts

Included Files

• STL

• DXF

• STEP

Print Settings

Recommended material:

• ABS

• ASA

Standard Voron-style print settings work well.

Manufacturing

Laser-cut all steel components from 2 mm steel sheet.

Deburr all edges before assembly.

Pay attention to magnet polarity before gluing the magnets into place.

Compatibility

This is a generic floating lead screw nut and should be adaptable to many printers.

Verify dimensions against your own Z-axis components before manufacturing.
