Tapered threaded brass inserts for 3D Printing Easy to set in an appropriately-sized hole in the part using a soldering iron. Numerous vanes and ridges around the insert allow plastic to flow between them, creating a tough bond with the printed part. This is a much more versatile, durable, professional, and attractive solution than "captive nuts" and other solutions commonly employed when the need for metal threads in printed parts arises. One primary advantage these provide is the ability to design and print assemblies in multiple component pieces that attach with metal fasteners. This means that you can create products larger than the print volume your printer supports, and that failed prints often result in less waste due to only one part of a larger assembly failing. This also typically results in more "polished", professional-looking designs.
