N42 6x3mm Round Black Nickel Coated Neodymium Magnets

N42 6 × 3 mm black-nickel neodymium disc magnets for Voron-style probes, panels, and compact magnetic mounts. These are small round NdFeB magnets with a near-black conductive nickel finish, sold individually so you can buy the exact count your build needs.

Why this magnet

• 6 mm diameter × 3 mm thick is the common round magnet size used across Voron and 3D-printer mods.
• N42 neodymium gives strong holding force in a tiny disc without stepping up to the more brittle, higher-pull N52 option.
• Black nickel coating gives a cleaner dark finish while keeping the magnet electrically conductive.
• Sold per magnet, not as a fixed kit or bulk pack, so spares and odd-count BOMs are easy.

Specifications

• Magnet type: round neodymium / NdFeB disc magnet
• Grade: N42
• Size: 6 mm diameter × 3 mm thick
• Finish: black nickel coating
• Shape: flat round disc
• Quantity: price is per 1 magnet

Intended use

Use these anywhere a build calls for a 6 × 3 mm round neodymium magnet: Voron TAP/Klicky-style probe assemblies, magnetic panels, printer mods, printed jigs, latches, closures, and small fixtures.

Gotchas

• These are not rubber-coated or plastic-coated magnets; the coating is thin black nickel.
• Neodymium magnets are brittle. Press-fit carefully and avoid letting loose magnets snap together.
• Check your BOM before ordering: this listing is N42. If your design specifically calls for N52, use an N52 magnet instead.
