Embedding Neodymium Magnets in 3D Prints – Smart DIY Applications

Take Your 3D Prints to the Next Level – with Magnets

Want to make your 3D prints more dynamic, modular, or interactive? Embedding neodymium magnets is a simple and effective way to add snap-fit closures, modular features, or magnetic mounts to your designs.

Common use cases include:

– Magnetic boxes or lids
– Interchangeable tool holders
– Snap-fit parts with magnetic alignment
– Game tokens or tabletop accessories
– Custom name tags or displays

Recommended Magnet Sizes

The best magnets for 3D printing are small but strong. Here are our top picks:

– 6 mm × 2 mm: popular for general use
– 8 mm × 3 mm: for stronger holding power
– 10 × 2 mm or 5 × 1 mm: for flat designs or thin walls

Make sure your design has the correct hole size with a tight press fit or space for glue.

Two Ways to Add Magnets

Option 1 – Glue after printing
✔ Model includes magnet slots
✔ Use superglue or epoxy to insert magnets later

Option 2 – Pause and embed mid-print
✔ Add a “pause at layer” command (e.g. in Cura or PrusaSlicer)
✔ Drop in the magnet and resume printing – the top layers will seal it inside

Best Practices

✔ Always check magnet polarity before gluing
✔ Use non-ferromagnetic tools (e.g. wood tweezers) to avoid shifting
✔ Consider coating the magnets to protect them in outdoor or humid conditions
