Want improve the connection strength between your project's 3D-printed parts, and also have the ability to screw in and screw out of your plastic parts? Instead of screwing into plastic, we recommend strong and reusable machine screws and heat-set inserts.
Heat set inserts are only reasonably priced and have a grooved outside, with theads on the inside. Originally they were designed for injection molded parts but they work fabulously for 3D printed plastic as well.
You could use a plain soldering iron to try to heat-press these in - Heat up the iron and use it to press the insert in, wait for it to cool, then use like a hex nut that's embedded inside the plastic.

How do heat set inserts improve strength of screw connections in plastic parts?
They provide a metal threaded bore inside the plastic while the knurled outside grips the material, increasing pullout strength and allowing repeated screw in and out.
Can these inserts be installed with a soldering iron?
Yes, heat the insert with a plain soldering iron and press it into the plastic, then let it cool to lock in place.
Are these inserts compatible with injection molded parts as well as 3D printed parts?
They were originally designed for injection molded parts but work well with 3D printed plastic too.
What sizes are available in this pack and what sizes are shown in the drawings?
The pack contains 10 brass heat set inserts. The listing mentions sizes such as M2.5, M3, M4, M5, M6 and M8 and provides drawings for these options.
Is there technical documentation or installation guidance available?
Yes, the product listing references heat set insert drawings for the sizes M2.5 to M8 that can guide installation.
