Product Description

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.

Specifications:

  • Thread Pitch: #8-32
  • OAL (length): 0.185" (short) / 0.312" (long)
  • D1 (top): 0.234"
  • D2 (bottom): 0.226" (short) / 0.208" (long)
    Please allow enough time for heat to transfer from the iron to the insert - maximum strength is achieved when the plastic can fully flow around the insert.

Durable fastener for 3D printed parts
Great way to add durable machine screw threads to 3D printed parts that get taken apart repeatedly. More durable than using sheet metal screws or wood screws. I used to mess with pausing the print and dropping in nuts to capture them, but these are much easier.I use a variable temp soldering iron 20 degrees C hotter than the hotend temperature of the filament, like 255C for PETG. Once set, I use something that doesn’t melt, like a flat piece of wood, to hold the insert down so it doesn’t pop itself up as the plastic cools.

These are my go-to for 3D printed parts. If you’re looking to bolt together larger assemblies, this is the way to go! I found that designing a hole with a diameter of 5.9 mm makes a great fit for these. Make sure you install them straight and flush!

Reviewed in the United States on August 31, 2019

These were bought to provide fastener threads for 3D printed parts. I made the hole in the printed part to be slightly larger than the smaller cylinder of the insert. Basically so the insert could slide partway into the hole in the plastic, until the larger insert diameter. I found a tip for my soldering iron and placed the insert on it. When hot the inert slid into the hole in the plastic. My first attempt was perfect because of doing the same with machined plastic parts. That was probably a fluke! You may have to make a practice part with several different diameter holes as a practice piece.

Great heat-set inserts with the exception of a few bad apples with rough threads in the bag. Not enough to make me not want to purchase them again though.
