Swpeet 300PCs 5 Values M2-M6 Female Thread Knurled Nuts Brass Threaded Insert Embedment Nuts Hydraulic Welded Joint Assortment Kit Perfect for 3D Printing & Injection Molding

They are very good and easy to use. They inserted into plastic very easy. Would have been nice to have the insert tools as part of the kit but for now using a pointed soldering iron without any problems

I bought these for a couple of 3D printed projects and they worked really well. Create a hole just a fraction smaller than the chosen insert, heat the insert up (I used a candle) and force it into the hole of the printed part, it is that simple. Nice selection of sizes good quality.

Drill saw bits very useful if you need to enlarge the hole

Good quality and does the job

I bought this pack solely for the m3 inserts for a 3D printing project I’ve been working on and they’re great to work with. If anyone else is going to use them like this I made the holes 4.7mm and used a soldering iron to put them in and it was super easy and they hold great. Highly recommend.

Ok.

Nice product. Would be good if they included a link to buy the sizes that I use the most.

hot iron insertion into 3d printed parts. really happy with kit

So far, i have only used with pla filament but really works nice. Makes the assembly so much easier and professional looking. I use my soldering iron to slowly push in the insert.
