Maker supplies that turn prints into working products

A printed enclosure, jig or robot rarely works on plastic alone. It needs threads that survive repeated assembly, fixings that clamp parts together, and hardware that lets things spin, slide, click or snap shut. This hub gathers that 3D printing hardware in one place and points you to the detailed guide for each family. For inspiration, read Printing Replacement Parts: Saving Money the Maker Way.

3D printing hardware by family

Heat set inserts

Brass inserts melt into a printed hole and leave a metal thread you can use again and again. Buy single knurled inserts from M2 to M8, start with the Heat Set Insert Starter Kit for M2 to M5, and fit the Soldering Iron Adapter Kit to your iron. Hole charts and installation steps are in our heat set inserts guide.

Screws, nuts and washers

The nuts, bolts and washers range covers stainless button head and countersunk screws, hex, thin and nyloc nuts, washers and galvanised square nuts. The M3 Fastener Starter Kit suits most printer parts, while thread forming screws drive straight into plastic. Unsure which approach suits your part? Our fasteners guide compares every method.

Bearings and magnets

The 608ZZ, 606ZZ, 625-2RS and 683ZZ bearings carry rotating parts, from spool holders to idlers, and small round neodymium magnets in 12 sizes make lids and tool mounts snap into place. Size tables and press fit tips live on our bearings and magnets page.

Steel balls and dowel pins

SS304 steel balls from 2 to 10 mm create click detents, rolling races and ball joints. Polished dowel pins in 2, 3 and 5 mm diameters make hard wearing hinge axles and alignment pins. Both come as singles or in assortments.

Here is how the hardware comes together in a typical project: a printed case for a single board computer with a screw-down lid and a magnetic cable hatch. Adjust quantities and lengths to suit your own design.

Maker supplies FAQs

What hardware should I buy first for functional prints?

Start with M3, the default thread for fan mounts, enclosures, printer upgrades and most functional designs you will download. The M3 Fastener Starter Kit and M3 Heat Set Insert Pack cover those jobs between them. Add bearings, magnets or pins once a project has moving parts, and step up to M4 or M5 for frames and brackets.

Is all of the hardware stainless steel?

Not all of it. The screws, nuts, washers, steel balls and dowel pins are stainless, mostly SS304, for good corrosion resistance indoors and out. The square nuts are galvanised steel, the heat set inserts are knurled brass and the magnets are neodymium, so check the product page when corrosion resistance matters for a build.

Can I buy just one or two parts?

Yes. Most inserts, screws, nuts, washers, bearings, magnets, balls and pins are sold individually, so a repair that needs two nuts only needs two nuts in the cart. Kits and assortments bundle popular sizes for less than buying each on its own, and the thread forming screws also come in packs of 100.

Do you stock hardware for printer builds and upgrades?

Many printer builds and upgrades rely on M3 and M5 hardware. Our M3 Thick heat set insert matches designs that call for an M3 x 5 x 4 insert, and the M5 Heat Set Insert Pack and M5 Fastener Starter Kit suit aluminium extrusion frames. Check your build's bill of materials for the exact sizes and quantities before ordering.
