ruthexM3 Threaded Inserts VORON - 100 Pieces RX-M3x5x4 Brass Heat Set Insert for Plastic Parts - Metric knurled Nuts - Insert by Heat into 3D Printing Components

These inserts are high-quality and have provided no issue so far with the printed parts on my 2.4 that I am rebuilding. Definitely consider these threaded inserts over some of the generic, cheaper ones you find.

If you're making anything which might be sold in California, or you just don't want to use any parts or materials which contain Lead or Cadmium, these are an excellent choice. And for such a reasonable price, why would you want to use anything else? The quality is as close to perfect as anything you'll find, and Ruthex also makes an excellent set of insert tools which fit nicely into many of the currently available soldering irons. For these reasons, I've purchased these in a range of sizes along with the Ruthex insertion tools. I can't recommend these enough, and have a hard time understanding why any manufacturer of brass inserts is still using brass containing lead and cadmium. Sadly, I don't know of any U.S. insert manufacturers which use lead free/cadmium free brass. I've actually called them and asked. Hopefully next year, RFK Jr. can start changing this. And I hope he does, because I'd like to start buying my inserts from U.S. manufacturers.

Inserts were used to modify the base of the GenMachine PC to rotate the PC 90 degrees from the factory mounting screws to change the position of the connections from the top to the side to relieve stress on the connections and improve the appearance of the setup.I used JB weld for plastic to fix the inserts at the base.

You will also appreciate having a set of soldering tips for installing these. I used https://www.amazon.com/dp/B08B17VQLD. The combination is a game-changer for creating screwed-together multi-piece 3D assemblies. For PET-G, and probably for other plastics, design the part with holes about 1.5mm larger than the desired screw. Put one of these on the appropriate soldering tip, wait a few seconds, then ease them into the hole, flush with the surface. Voila! Strong and secure threaded holes that can be easily assembled/disassembled repeatedly.

These were exactly what I needed for a 3d printed violin I made! They're made well and can hold a great amount of pressure! The chin rest and the neck (both grey pieces) are being held with these. My only real problem with the product is the fact that it didn't come with the solder tip needed to melt these in and I had to buy it separately. It seems like something so simple should be added with this.

Spend on the inserts, not on the heat tool to insert them.These are great: very clear dimensions, chamfered, hatches in different directions.Check YouTube for reviews, comparisons etc.They cost maybe 5-10x more than the cheapest but your parts and time printing them is worth the few cents extra, including if you build a printer or something complex and the heat inserts are crappy.

Bought these for 3D printing, I use a wood burning pen to melt the hole and then push the fitting into it. It works great, highly recommend it for anyone with similar projects

I am working on an EVA3 tool head for a Zero G Mercury 1.1 conversion and got these since they were the correct size from the bill of materials. They came neatly packaged in a bag and work as expected. They were easy to install with a heated soldering iron to push them in. The grip seems strong and the M3 screws thread perfectly through the inserts. Extremely happy with these and looking forward to using them to secure more prints and help me finish my conversion!

Working good good quality and good delivery

Was soll man groß zu Bohrern schreiben

Landen in fast jedem technischen 3D druck den ich mache, halten super und sind mit einem Lötkolben einfach zu installieren. Die Verarbeitung ist ausgezeichnet und die Gewinde sind perfekt.

Just great

Utilisé dans une pièce imprimé en 3D. J’ai utilisé un fer à souder pour placer l’insert, et tout fonctionne super bien, il est vraiment solide, la taille me convient parfaitement
