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

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

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.

Good quality and does the job

Alles Super

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.

Ok.

good

Très pratique pour la modélisation 3d.
