ruthex M3 Threaded Inserts VORON - 100 Pieces RX-M3x5x4 Brass Heat Set Insert for Plastic Parts - Metric knurled Nuts - Insert by Heat into 3D Printing Components

Overall, I’m very happy with these heat inserts. They shipped quickly and arrived in good condition with no issues. In use, the machining appears to be high quality and the knurling is clean and consistent. Screws thread in smoothly without binding or cross-threading. I primarily use these for 3D printed parts and have not experienced any fitment or durability problems. They perform exactly as expected and I would recommend them to anyone installing threaded inserts in 3D prints.

Sizing was spot on for Sherpa heavy build. Easy to use and strong hold.

These inserts worked great for my 3d print they fit perfectly and were very easy to install and definitely hold strong I used these inserts on petg filament I have put it to the test and so far they haven't gave out just try not to over torque them ..

Worked great, Ruthex stuff is well documented

Quality product that works as expected/as advertised.

Right size easy to work with good value

This is going to sound trivial, but it didn’t come with the setting tip. These are some great inserts that work amazingly well. The fit is unmatched. I’ve tried other inserts and a lot of the cheaper ones have some sort of issue, either they don’t sear properly for some reason or they have burs or the threads either aren’t there or are cross threaded. The only thing that would make these better is if they came with the tip, otherwise great value.

best threaded inserts on the market by far! creates a VERY strong/secure anchor point!

Not a very advanced product so not much to say honestly but they work really well for 3D printed parts and is way better than the cheaper type that has this entirely vertical pattern on them. These comes with essentially threads that digs into the plastic really well. But maybe the best part, they come with a 3D model. Honestly bit of a miss on their part to not market that because it's really convenient to get a perfectly scaled 3D model you can insert into assemblies in cad. It's such a great detail that just makes these nice to work with. Simple addition that should be standard.
