Brass Heat-Set Inserts for Plastic - M3 x

3mm - 50 pack

PRODUCT ID: 4256

Wanna improve the connection strength between your project's 3D-printed

parts, and also have nice clean surfaces? Instead of gluing bits together, or

screwing plastic screws directly into your 3D prints, use strong and reusable

machine screws and heat-set inserts. Heat set inserts are only a few cents a

piece 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. We strongly recommend our heat-set insert

tool for soldering irons because it's really hard to insert them straight otherwise

and you risk damaging your print!
