3D Models with Permanent Magnets to Print

This collection gathers 3D models built around permanent magnets: small generators and alternators, floating toys, fridge magnets, and holders that grip tools or lights. Most of them are printed as housings or frames that hold a magnet in place, so the printed part and the hardware have to match. It is useful if you already print functional parts and want to see how other makers design around a magnet. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«3D Models with Permanent Magnets to Print»

The models differ mainly in what the magnet does. In generators and alternators it moves past coils, so the design is about a rotor, a stator and a shaft that turns without wobbling. Floating toys use opposing magnets to hold a part in the air, which makes the geometry and the spacing between magnets the whole point. Fridge magnets, cursor-shaped magnets and similar pieces are simpler: a printed shell with a recess for one or two magnets.

When you open an author's page, look at the size and scale first, then at the number of parts and how they assemble. Check whether the model was designed around a specific magnet shape and thickness, since a recess that is too deep or too shallow changes how the part behaves. Read the material and settings the author lists, and look at photos of real prints to judge wall thickness and tolerances. If the model has moving parts, see whether supports are needed and where they would sit.

To find more, try related wording: magnetic, neodymium, levitation, rotor, stator, coil, fridge magnet, magnetic mount. Searching for the object rather than the magnet often helps, for example generator conversion, whiteboard holder or shower curtain clip. You can also browse neighbouring topics such as electronics, toys and household accessories, where magnets appear as a small part of a larger design.

FAQ

Perguntas frequentes

What do I need besides the printed parts?
Usually the magnets themselves, and sometimes screws, bearings, wire or a shaft. The author's page normally states the magnet dimensions and the extra hardware the design expects.
How do I keep magnets in place in a printed part?
Many designs use a recess sized for a press fit, and some add a drop of glue or a printed cap. Check the stated magnet size and the clearance in the model before printing.
Can I scale a magnetic model up or down?
Scaling changes the recesses, so a magnet that fits the original size may no longer fit. If you scale, measure the cavity and adjust it, or keep the original size.
Which filament works for these parts?
It depends on the load and the environment; the author's notes usually name a material and settings. For parts that flex or take force, follow those notes rather than substituting blindly.
