Decent quality
Very good product, I get through a fair few of these in my 3d prints, these are as good as any others, they set in well and stay in well, the threads are nice and clean and accept the m3 bolts easily.

Good quality inserts
I've found myself buying this brand in particular. They are good quality. I have bought large quantities from CNC Kitchen, but sometimes I've needed sizes I didn't have, in a hurry, so I end up in here - choose these every time. I don't put them in hot as I don't personally think that's a good idea. I fit mine using a toggle press and add they go in, you can see them rotating and effectively cutting themselves into the material. A royal pita to get out of something is wrong, so I know they work!

Work well enough, does what they say it does well.

Surprisingly effective
A little bit of practice is useful to start with, making different-sized holes to see what works best for you, and to get a good temperature and technique for inserting. After that, these are very effective at holding screws to join printed parts together.

Die Gewindeeinsätze sind eine super Ergänzung für alle, die viel mit 3D-Druck oder Kunststoffteilen arbeiten. Die Messing-Einsätze lassen sich sehr sauber einsetzen und bilden stabile, langlebige Gewinde, die auch häufiges Ein- und Ausschrauben ohne Probleme mitmachen. Die Qualität der Messing-Gewindehülsen ist wirklich gut – sie sitzen fest, drehen sich nicht mit und halten perfekt in PLA, ABS oder anderen thermoplastischen Materialien. Die Lieferung im 50er-Pack ist ideal, wenn man oft Ersatzteile, Prototypen oder funktionale Komponenten herstellt. 👍 Vorteile: • Einfaches Einpressen / Einschmelzen • Saubere Gewinde mit guter Festigkeit • Viel Zubehör für wiederholte Nutzung • Gute Preis-Leistung Ein super Produkt für Hobby-Bastler und professionelle Nutzer gleichermaßen. Klare Empfehlung!

Acheté pour l'impression 3D. Très pratique. Les tolérances indiquées sont respectées. Rien à signaler.
