in-saiL 100pcs/lot M3x4.0mm, OD4.6mm Heat Staking Threaded Insert Quik-Tek Brass C3604

Will use the as inserts on a 3d printed device for a threaded capture where the plastic wont accept the tapping of machine screw threads.

They do what they are supposed to do! What can I say, they are as described.

Very easy to install with use of a soldering iron and some pressure applied to a 3d printed part. Used mostly with PLA parts for mating enclosures.

If you 3d print you need these...

Love these things, theyre so good I use them so much I keep coming back for more. 10/10 will threaded insert again

too small for voron parts

If you are still using captured nuts on your prints give these a shot. Incorporating them into your designs is fun, not much harder than captured hex nuts and once theyre in, they stay in.

Worked for my 3d printing projects. Easy to insert, sits tight.

These are perfectly sized

Easily melts into a 4mm hole in a 3d print, and holds way better than threading into the plastic.
