Ich habe die 3D Druck Messing Muttern (M3x4x5mm) in meinem letzten 3D-Projekt verwendet und bin sehr zufrieden mit ihrer Qualität. Die Einsätze sind sehr maßgenau gefertigt, sodass sie sich problemlos und ohne Spiel in die gedruckten Teile integrieren lassen.Dank der soliden Messingverarbeitung halten die Gewinde zuverlässig und sorgen für eine stabile Verbindung zwischen den Bauteilen. Die Installation verläuft unkompliziert – ein kurzer Hitze- oder Druckvorgang genügt, um die Muttern sicher im Kunststoff zu verankern. Wer auf der Suche nach hochwertigen Gewindeeinsätzen für präzise 3D-Druck-Projekte ist, sollte hier zugreifen.

Install fine, no tear-outs I'd blame the knurled nut for.Every one I've used all the threads and forming seem good.

I really like the ones with the smooth collar on one end to get them situated correctly before sinking them into place.

I bought these and used them to install 3-D printed parts on to an electric unicycle and they did the job pretty well. They are a little bit expensive I think but good quality too.

These threaded inserts were exactly as described and every one of them worked fine. I used these on a Voron 3D printer build and used the last one just today. Every one was properly threaded and worked as expected. Being able to purchase from Amazon with quick delivery was worth the slightly higher price compared to buying direct from an importer.

I needed more heat set inserts for my Voron projects. These seem to fit the spec and worked well for me.
